How to reveal the hidden space

  • macOS Mojave or later: You may see a lot of hidden space if you deny DaisyDisk access to your Calendar,
    Photos, Contacts and other privacy-sensitive folders. The system shows you the corresponding dialogs and remembers your choices the first time you scan your disk.
    In case if you deny the access, the size of hidden space will grow by the corresponding amount, while some folders on the map will appear empty.
    To override your previous choices, you can open System Preferences > Security & Privacy, go to the Privacy tab and add DaisyDisk to the “Full Disk Access” list.
    Then rescan your disk. DaisyDisk will not read the actual content of your private data, only the metadata (such as name and size).
    This approach is recommended in Apple’s official WWDC 2018 video which mentions DaisyDisk as an example (begin at 9:22).
  • Use the scan as administrator command. The hidden space should disappear, or become significantly smaller by size. And in reverse, some other folders will grow in size correspondingly, and restricted files and folders will become visible here and there on your disk.
  • Note that some small amount of hidden space (a few GB) may still remain even after scanning as administrator. This is normal. Usually this space is used by the file system itself.
  • When you delete a file or folder and Time Machine is turned on, the system may not delete the files entirely, but move them to the purgeable space,
    causing it to grow by the corresponding amount. However, the system often delays updating the size of the purgeable space by few minutes.
    During this delay, you may temporarily see the hidden space being “borrowed” by the equal amount.
    DaisyDisk will automatically refresh (without rescanning) the numbers or hidden and purgeable space after the system updates them globally.
  • Also, just after you delete the purgeable space,
    you may temporarily see the hidden space being “borrowed” by the corresponding amount.
    Please allow some time (from few seconds to few minutes) before the system completes reclaiming the purgeable space in the background.
    The purging may be additionally delayed if the Time Machine is in process of backing up.
  • If you are using third-party backup tools such as Carbon Copy Cloner (CCC), they can create their own file system snapshots.
    Unlike the Time Machine snapshots, the third-party snapshots are not counted
    toward the purgeable space, but toward the still hidden space.
    You can check for presence of any third-party snapshots using command in Terminal.
    In order to reveal and delete such snapshots, please use the corresponding third-party apps. For example, here’s how you delete a snapshot created by CCC.
  • Large amounts of hidden disk space may also indicate errors in the file system. You can use the Disk Utility to verify and repair your disk’s integrity.
    In some cases, you may need to boot your Mac in Recovery mode and run the Disk Utility from there.

    In the most obstinate cases with APFS disks, you may need to use the lower-level fsck_apfs command-line utility to verify and repair the APFS volume from the Recovery mode.

    Similarly, for HFS+ disks, you may need to use fsck_hfs. Beside verifying, you can use it to repair the HFS+ catalog file. WARNING: this operation may not be safe for your data! You should make a full backup of your disk before trying. Please seek professional help on the matter.

  • Some backup tools are known to leave garbage in folder. Check it out with the Terminal app.
  • If nothing of the above helps, please .

DaisyDisk 2 goes beta

It’s been a long time… How have you been?

Today we’re ready to introduce you to our newest creation, DaisyDisk 2 β:http://cl.ly/3Wj7

What has changed since DaisyDisk 1.5.3? Almost everything!
In fact, we’ve build most parts of DaisyDisk 2 from scratch.

Well, really, take a look at this short whatsnew:

  • In-app file deletion
  • Brand new UI, created from scratch on Core Animation
  • Ability to scan several disks/folders at a time
  • Scan results are remembered while the application is running, can be forgotten to free memory
  • More informative disk descriptions
  • Redesigned disk usage gauge
  • Scanned folders are added to the list of sources
  • New logic for scanning as Administrator (was Super-User)
  • New About window informs you about recovered space totals, allows you to tweet your results
  • Updated Feedback window
  • Redesigned Crash Reporter (we hope you’ll never see it)
  • New error handling logic (yep, built-in dialogs suck)
  • Major under the hood changes and tons of tweaks you’ll unlikely ever need to know about

What’s known to be missing/broken:

  • We haven’t switched to a new registration system, but DaisyDisk 2 beta accepts DaisyDisk 1.x license keys
  • Localization is dropped (we’re not accepting localizations for some time, sorry…)
  • Help file is missing (we haven’t finished working on it yet)
  • A few more things…

The beta expires on December 31, 2010.

If you buy now, DaisyDisk 2.0 will be a free upgrade for you (you’ll need to get a new key online once the final version is released).

Upgrade policy for existing users remains unchanged:
$9,95 unless your license key has been issued before October 15, 2009 or after September 1, 2010. Otherwise free.

Enjoy…

Образы дисков

При работе c образами дисков не следует забывать, что они — всего лишь контейнеры для данных. Они могут быть целостными файлами фиксированного размера (например, образы ISO), сжатыми файлами (что-то вроде больших ZIP файлов) или же пакетами (наборами небольших файлов, представленных в форме целостного объекта), как в случае с растущими пакетами-образами.

Будучи смонтированным, каждый образ сообщает три значения: емкость, количество свободного и занятого места. Проблема заключается в том, что эти значения являются виртуальными и могут вводить в заблуждение (это не глюк DaisyDisk, это данные предоставляемые OS X).

Для образов фиксированного размера емкость обычно соответствует размеру файла образа. Свободное и используемое место указывают на то, какой объем данных образ способен вместить, хотя размер образа диска не меняется вне зависимости от того, пустой он или полностью заполнен.

Самое интересное начинается при работе с растущими образами дисков. В отличие от образов фиксированного размера, размер которых вроде как фиксирован, растущие образы могут расширяться при необходимости. Виртуальная емкость растущих образов может даже превышать объем свободного места на диске, на котором образ хранится. Виртуальное значение свободного места же, наоборот, ограничено объемом реально имеющегося свободного места на родительском диске. Вот здесь-то и начинается веселье.
Объем занятый вычисляется как разница между емкостью и объемом свободного места. Потому в случае, когда виртуальная емкость образа превышает реально доступный объем места на родительском диске, можно увидеть значения использованного пространства, имеющие мало отношения к тому, какой объем данных уже записан в образ.

Не забывайте, что растущие образы только увеличиваются, никогда не сжимаясь самостоятельно. Проще говоря, удаление файлов с такого образа с целью сокращения размера образа результата не даст. Для сжатия придется воспользоваться консольной командой hdiutil compact.

About APFS and Mac OS Extended

Disk Utility in macOS High Sierra or later can erase most disks and volumes for Mac using either the newer APFS (Apple File System) format or the older Mac OS Extended format, and it automatically chooses a compatible format for you.

Identify the current format

If you want to know which format is currently in use, use any of these methods:

  • Select the volume in the Disk Utility sidebar, then check the information on the right. For more detail, choose File > Get Info from the Disk Utility menu bar.
  • Open System Information and select Storage in the sidebar. The File System column on the right shows the format of each volume.
  • Select the volume in the Finder, then choose File > Get Info from the menu bar. The Get Info window shows the Format of that volume.

Automatic registration by detection of Mac App Store purchase

If you have previously purchased DaisyDisk in the Mac App Store then the stand-alone edition of DaisyDisk will detect your purchase and become registered even without a license key. After this automatic registration happens, it’s safe to delete the Mac App Store edition of DaisyDisk.

Note that this automatic registration will only work if the Mac App Store edition of DaisyDisk has been installed on your Mac. On a new Mac, or after a clean reinstallation of the macOS, you will first have to reinstall DaisyDisk from the Mac App Store. To avoid this inconvenience, we recommend our Mac App Store customers to obtain a free permanent stand-alone license.

See also DaisyDisk EULA for more detail on the terms of the license.

DaisyDisk 4.5 Officially Released

Now it’s official: the long awaited DaisyDisk 4.5 is finally out!

It’s an important update, that took us a long time to research and develop. The main new feature — the extended support of the new Apple File System (APFS) and addressing the top questions about macOS High Sierra and APFS that we have received.

What’s new:

  • Extended support of the new Apple File System (APFS) on macOS High Sierra, in particular:
  • You can now see the “purgeable space” — the disk space taken by the local snapshots of Time Machine and other caches, which cannot be scanned, but can now be identified inside the “hidden space”.
  • And you can now reclaim that “purgeable space”.
  • Added display of the “free space” in the right sidebar list, along with the estimation of available space, that is, “free + purgeable”.
  • Added display of the space taken by “other volumes” in the same APFS container, inside the “hidden space”.
  • Lots of bugs fixed.

Please upgrade by downloading the new version from our website, or by using Check for Updates… menu command from within the app.

The updated user manual can be found here.

Registering your DaisyDisk License

After you purchase the license in our online store, you will receive the link
to your license. The easiest way to register is just to click that link, provided that you have downloaded
and unzipped the DaisyDisk app first (otherwise the link will not work).

If for some reason the automatic link did not work, you can always register manually. Go to the DaisyDisk > Registration… menu and enter your registration information into the form.
No need to type, just copy-paste both registration name and the key from the registration letter you’ve received.

After your registration data are accepted (see those cute green checkmarks?), click Register to complete.

DaisyDisk 4.0.3 fixes the Sparkle vulnerability, adds German and Russian languages

DaisyDisk 4.0.3 stand-alone version is now live, the Mac App Store version is submitted for review and is coming soon.

Update! 🙂

This update fixes the recently revealed Sparkle vulnerability, though at the time we were already using HTTPS so DaisyDisk users were not likely affected. Beside th fix, we re-added German and Russian localizations. Full change log here.

Please note that if you are using stand-alone DaisyDisk 4.0.1 on El Capitan, you’ll have to update manually, that is, by downloading and replacing the app. The built-in updater was unfortunately broken in DaisyDisk 4.0.1. It should still work fine though on OS X Yosemite.

DaisyDisk 2, the final

We’ve done it. After being in development for more than a year, DaisyDisk 2 is finally released and is available for everyone.

Version 2 is a major improvement over DaisyDisk 1 which many of you know and love: all main parts of the application have been re-written, refactored and improved:

  • In-app file deletion (yes, finally…)
  • Brand new look, the UI is rewritten on Core Animation
  • Ability to scan multiple disks simultaneously
  • Scan results are remembered while the application is running, can be forgotten to free memory
  • More informative disk descriptions, icon overlay for read-only volumes and folders
  • Redesigned Disk usage gauge
  • New scan progress indicator for the Dock icon
  • Scanned folders are added to the list of sources
  • New logic for scanning as Administrator (was Super-User): now you can only scan local volumes and folders
  • FileVault support
  • Support for multi-touch gestures (refer to manual for the complete list)
  • New error handling logic (yep, built-in dialogs suck)
  • New registration system (DaisyDisk 1.x keys will not unlock 2.x)
  • Redesigned About, Feedback, Crash Reporter windows
  • Twitter integration (quite useless, but fun 🙂
  • Major under the hood changes and tons of tweaks you’ll unlikely ever need to know about 🙂
  • Localization is temporarily dropped (we’re not accepting localizations for some time, sorry…)

Not bad, huh…

DaisyDisk 2 is available in two versions: stand-alone (classic shareware) and Mac App Store. You can read more about them in this document.

Our upgrade policy remains unchanged: free upgrade if you purchased a license before October, 15 2009 or after September 1, 2010. $9.95 otherwise.

Ok, but how do you know if your license can be upgrade freely or not? The easiest way to do so is ask DaisyDisk itself. Just download and run the application and it will guide you through the rest of the process.

Now a small FAQ:

  • DaisyDisk 1.5.3 is the final version of DaisyDisk 1.x; we still provide support for it, but don’t expect future updates.
  • DaisyDisk 2.x will continue to evolve, we plan some very promising improvements. And no, it won’t make coffee.
  • We do not offer refunds or redeem codes for users willing to migrate to the Mac App Store for free.
  • In the future stand-alone versions of DaisyDisk may have extra features, not available in the App Store as Apple’s review policy prevents us from adding certain functionality.
  • The final release of DaisyDisk 2 stand-alone is not unlocked with DaisyDisk 1.x keys, they must be upgraded online. Contact support if you have any upgrade-related issues.

So, what’s next? First of all, we’d liked to take a small break and finish some stuff.
We’ll also start working on a side project (no details right now, sorry…) along with preparing DaisyDisk 2 updates. There’re lots of things we have to do, especially with an emergence of Mac OS X 10.7 Lion which plans to be a very interesting OS.

Stay tuned.

Yours truly, DaisyDisk Team.

Free space not appearing after deletion

Contrary to what you may expect, deleting files in macOS may not immediately produce free space.
If Time Machine is enabled on your Mac (which should always be recommended), it will regularly
back up your entire disk’s content in so called local snapshots.
The snapshots are designed in such a way that they don’t consume additional disk space if there is little change
compared to the previous backup.

So, when you delete a file, its copy may still be retained in the local snapshots,
and still consume the same amount of disk space. In result, the free space will not grow, but the amount of
hidden space, and more specifically, the purgeable space,
will increase by the corresponding amount. This is normal — macOS will eventually automatically reclaim the purgeable space when the apps request more disk space.
Alternatively, you can forcedly purge it with DaisyDisk.

Time Machine Volumes

A comprehensive Time Machine FAQ can be found here.

Even though DaisyDisk is able to scan Time Machine volumes, it does not allow you to remove any files from it. Apple does not welcome altering backups for a reason, and even in Finder you cannot make any modifications to your backups.

The only good way to delete anything from Time Machine backups without ruining them is using the Time Machine itself.

Never forget that by its nature the Time Machine will expand until it takes all space on its volume, so storing anything else on the same volume is not a good idea.

If you’re 100% sure you need to reduce Time Machine’s backup size by removing large files or folders from it, just follow the instruction below.

Scan the Time Machine volume. It usually takes 15 to 40 minutes depending on the way the disk is connected (USB, FireWire or Wi-Fi) and the number of stored backups.

Unless absolutely necessary, do not scan Time Machine volumes as administrator, because it will likely take 3 or 4 times longer.

By their nature Time Machine backups contain lots of hard links which greatly reduce the disk space taken by backups while making each snapshot a complete copy of your system. DaisyDisk only counts the first encountered hard links and thus gives you a more accurate picture of how large each snapshot actually is.

Once a candidate for exclusion from your backup is found, remember its name and backup date (backup folder names have YYYY-MM-DD prefixes, e.g. ), launch the Time Machine from your folder and browse to the date. With the regarded folder selected, choose the Delete All Backups of Selected Folder command from the menu:

That’s all. Don’t forget to configure the Time Machine to exclude the folders you don’t want to backup.

How stuff works

  • If you see a disk in Finder, you can scan it in DaisyDisk.
  • The application calculates the physical file size, not logical one (except on network drives).
  • Bundles appear as solid objects, just like Finder.
  • DaisyDisk updates the amount of free space for each volume in real time, this may be handy for monitoring.
  • Scanned snapshots may take hundreds of megabytes of your RAM, so if you’ve got only 2GB of RAM or less, at times you may want to tell DaisyDisk to forget some scan results.
  • DaisyDisk automatically updates the disk map if you delete any files in-app, but it cannot track the changes you make from ther Finder or other software.
  • The build-in preview is powered by the Quick Look, so it also picks up any plugins you install.
  • (hidden space) and …smaller objects… are virtual items and work in a different way than files or folders.
  • You can scan FileVault-protected disks, but knowing a bit of stuff under the hood never hurts.

Удаление файлов

  • Файлы в Сборнике остаются в целостности до тех пор, пока вы не нажмете Удалить.
  • DaisyDisk изо всех сил старается предотвратить случайную потерю данных, но будьте бдительны: дважды проверьте список файлов в Сборнике перед удалением.
  • Файлы, удаленные из DaisyDisk исчезают навсегда. Единственная возможность их восстановить — использование специальных программ для восстановления данных после удаления.
  • Заблаговременно очищайте Корзину: там могут скапливаться десятки гигабайт мусора.
  • Перемещение файлов в Корзину не освобождает место на диске, для этого Корзину нужно очистить.
  • Удаление файлов на образе диска не уменьшит размер самого образа.

DaisyDisk 2.1 is out

Standalone version is available for immediate download and the app store one has just been submitted to Apple for approval.

DaisyDisk 2.1 features two localizations (folks from Germany and Russia, rejoice) and greatly improved support for OS X Lion. Sooth to say even previous versions of DaisyDisk have been Lion ready, but even minor glitches are annoying, so we’re getting rid of them. As well as trying to take advantage of new technologies 🙂

Starting from version 2.1 DaisyDisk is no longer Leopard compatible, you’ll need to use version 2.0.7.1 (available on our support page) if you still rely on PPC/Leopard.

What’s new in 2.1

OS X Lion:

  • Fullscreen mode
  • Window state resume
  • Volumes encrypted with FileVault 2 are clearly marked as such, support parallel scan

Other changes and improvements:

  • Disk usage gauge and sidebar scale up according to the window’s size
  • Removed main window’s bottom bar: less vertical screen space, looks better on Lion
  • New navigation for returning to the list of disks and folders
  • Updated all buttons and controls with more polished graphics
  • Fixed some minor graphic glitches on OS X Lion
  • Updated third-party frameworks to the most recent versions
  • Help file updated to reflect most recent changes
  • Localization program is back: DaisyDisk now speaks Russian and German, more languages to come soon
  • Tons of smaller fixes and tweaks

Other updates will follow during next months.

Stay tuned.
Yours truly, DaisyDisk Team.

DaisyDisk 2 debuts in Mac App Store

DaisyDisk 2 debuts in Mac App Store and is available for purchase right now (direct link).

Now a small FAQ:

– I own a license for DaisyDisk 1, but it is not shown in the Mac App Store

The Mac App Store has its own mechanism of registration and updates for apps, so it does not recognize the previously bought DaisyDisk licenses. The only way to make DaisyDisk managed by the App Store is to buy it again via the App Store.

Note: DaisyDisk may appear Installed in the Mac App Store, but the app will still not be managed by the App Store (updates, sharing the license across your Macs) unless the app was bought via the Mac App Store.

– I own a license for DaisyDisk 1, how can I get the discounted upgrade?

The discounted upgrade will be available only as a stand-alone app and not as a Mac App Store app. You’ll be able to upgrade to DaisyDisk 2 once it’s available on our site. The upgrade policy remains the same: $9,95 unless your license key was issued before October 15, 2009 or after September 1, 2010. Otherwise free of charge.

– Can I upgrade from a license for DaisyDisk 1 to version 2 for the Mac App Store?

The only way to do it is to buy the app via the Mac App Store at the full price. You cannot get a discounted upgrade from your DaisyDisk 1 to Mac App Store version 2, it’s technically impossible.

– What’s the difference between the MAS and stand-alone versions?

The App Store version does not support scanning as administrator: the feature was removed to comply with Apple’s app submission policy. The MAS version does not support OS X 10.5 (no luck for PPC users) and update/registration mechanisms are changed to ones provided by Apple. Future versions may differ even more, a lot depends on Apple.

– If I buy the App Store version of DaisyDisk right now, will I be able to exchange it for the stand-alone version later?

Sharing knowledge: win one of 12 great books

Hi.

There’re some great news we’d liked to share.

We are giving away 3 promo codes to DaisyDisk. Nah… Boring…We are giving away 5 $10 iTunes cards… so you can download some annoying tunes…
Seen this stuff a million times, no cool. Let’s try something different.

This week we are celebrating the successful start of DaisyDisk 2 by giving away 12 great great books. Most of these have already become live classics and well worth reading by just any person interested in design, data visualization and building software. Almost $500 for us — priceless knowledge for you.

Let’s see what’s in:

The Visual Display of Quantitative Information, Envisioning Information, Visual Explanations by Edward Tufte. The best design books ever. Period.

by Stephen Few and The Wall Street Journal Guide to Information Graphics by Dona Wong. While not as mind-blowing as Tufte’s books these are worth reading for any person interested in information visualization.

by Alan Cooper and Kim Goodwin — essential reading for every interaction designer or software developer.

Designing Interactions by Bill Moggridge, one the most inspiring books we’ve ever read. Great stories behind cult products like Mac, computer mouse or PalmPilot.

Emotional Design: Why We Love (or Hate) Everyday Things by Norman. The name is quite self-explanatory. What we can add is that it seriously affects the way you’ll start looking at things after reading it.

Rework and Getting Real by 37signals, an icy shower for startupers and beginning software developers. Two of the few books about business that won’t make you asleep.

Tapworthy: Designing Great iPhone Apps. An essential book for iOS developers.

Not bad, huh?

Any of these books can be yours, no matter if you are in New York, Munich or Moscow. Refer to this article on MacStories for details.

Why are we doing this? We’re surely promoting our software, DaisyDisk, but that’s not all.
We believe we can make the world a better place by sharing books we’ve learned a lot from. So, if you happen to win one, improve your design skills and contribute back by creating a great website or application, that would be the best investment for us. Spending the same resources on buying ADs is merely useful for anyone 😉

Yours truly, DaisyDisk Team.

Time savers

  • Cmd-clicking any file or folder in DaisyDisk reveals it in Finder.
  • Using keyboard shortcuts and multi-touch gestures can boost your productivity.
  • Being a native Mac application, DaisyDisk supports drag and drop: you can drag disks or folders into the window to scan them, and drag and drop files to the Collector in order to collect them for further deletion.
  • You can scan multiple disks and folders at the same time.
  • DaisyDisk automatically prevents parallel scanning of multiple volumes of the same disk and scans them one by one when it is more beneficial.
  • Scanning as administrator at all times is counter-productive unless you have multiple user accounts on your Mac.
  • Star the folders you scan often.
  • Scanning time of a disk only depends on the number of files on that disk, not on its capacity.
  • Typical scanning time for a Mac HD volume is ~5 minutes.
  • Time Machine volumes usually take 15 to 45 minutes to scan due to the huge number of files they contain.

DaisyDisk 3 and app sandboxing

Since its very introduction in OS X, app sandboxing has been a pain in the butt for both developers and users. Developers have spent wonderful weeks or even months adopting their software to the new requirements, and users have surely loved the new for-the-sake-of-your-own-security dialogs.

While no doubt being a good idea in theory, Apple’s sandbox implementation leaves much do be desired, not to mention it’s ridden with bugs, which really hurt end users’ experience.

For example, sandboxed applications cannot unmount USB drives even after receiving full access. The bug has been reported to Apple months ago, but it’s still there in Mavericks. A new issue introduced in Mavericks is app’s inability to operate correctly if the sandbox access is granted by drag and drop. The open dialog works, but drag and drop, Mac’s natural way of interacting with things, doesn’t work correctly in Mavericks.

We, as developers, cannot fix sandbox bugs, but we can do one thing: offer all our customers a sandbox-free version of DaisyDisk, which solves all these problems once and for all. Just download DaisyDisk app directly from our site and it will pick up your Mac App Store registration data. In addition to being sandbox-free, the stand-alone version provides some extra features you may find useful.

DaisyDisk 4.5 Officially Released

Now it’s official: the long awaited DaisyDisk 4.5 is finally out!

It’s an important update, that took us a long time to research and develop. The main new feature — the extended support of the new Apple File System (APFS) and addressing the top questions about macOS High Sierra and APFS that we have received.

What’s new:

  • Extended support of the new Apple File System (APFS) on macOS High Sierra, in particular:
  • You can now see the “purgeable space” — the disk space taken by the local snapshots of Time Machine and other caches, which cannot be scanned, but can now be identified inside the “hidden space”.
  • And you can now reclaim that “purgeable space”.
  • Added display of the “free space” in the right sidebar list, along with the estimation of available space, that is, “free + purgeable”.
  • Added display of the space taken by “other volumes” in the same APFS container, inside the “hidden space”.
  • Lots of bugs fixed.

Please upgrade by downloading the new version from our website, or by using Check for Updates… menu command from within the app.

The updated user manual can be found here.

Revealing purgeable space in DaisyDisk

Starting from macOS High Sierra and APFS, the purgeable space is located outside of any scannable area, even with raised permissions.
Instead, DaisyDisk provides a macro-level view and deletion of the purgeable space.

After scanning, you can see the purgeable space when you expand the hidden space item.

Before macOS High Sierra, the main component of the purgeable space — the local snapshots of Time Machine —
could be revealed in restricted folder at path after scanning as administrator.

In disks overview, DaisyDisk includes the purgeable space into the free space, exactly as Finder does.
This allows you to understand how much space is maximally available on a disk, at a glance.
