Improved the appearance in dark mode.
Fixed a bug that caused incorrect filtering behavior in the review window when the search query was edited in the middle of the string.
Fixed a bug that caused the review window to look weird when the search query found no matches.

1.3.3 - June 8, 2025
Added support for multiple selections in the review window.
Control-click or right-click a file group in the list to show a context menu with options to copy the file name or file path, and more.
Shift-click or Command-click to select multiple file groups in the list, then perform operations on all selected items using the context menu (see above) or the “x” or “.” keys.
Use the search field in top-right corner of the window to narrow the file groups displayed in the list, then select some or all of the rows and use the tips above to perform operations on the selected items.
Click a column header in the file group list to change the sort order. Click the same header a second time to change the sort direction.
File Is Busy - If a file is marked as “busy,” it will be skipped. You can manually clear the “busy” bit on a file by running this command from the Terminal:
SetFile -a z myfile.txt

Q: Does Hyperspace support Family Sharing?
Hyperspace’s “Lifetime Unlock” as well as the auto-renewing “Monthly Subscription” and “Annual Subscription” do support Family Sharing.
Q: Hyperspace did not find much space to reclaim on my Mac. How can I improve this?
The best way to find more space to reclaim is to allow Hyperspace to scan more files. Hyperspace has many settings that will expand the scope of scans. Here are some settings changes you should consider if you want to find more space to reclaim:
If a lot of your files are in cloud storage (e.g., iCloud Drive, Microsoft OneDrive, Google Drive, etc.), consider changing the setting that will allow Hyperspace to access cloud storage during scans.
If you have a lot of data in “package” files such as Apple Photos libraries, iMovie libraries, and so on, consider changing the settings to allow Hyperspace to scan and reclaim files inside packages and allow access to Photos libraries.
If you want to leave no stone unturned in your search for disk space to reclaim, consider changing the setting that will allow Hyperspace to access “Library” folders.
If you’ve tried all of this advice and Hyperspace still doesn’t find much space to reclaim, then congratulations on your excellent data hygiene!
The divider between the top and bottom panes of the Review Window is resizable. Click and drag the divider to change the relative sizes of the panes.

Interface settings:
Foreground notifications - Send notifications even when Hyperspace is the active, foreground application. This setting has no effect unless notifications are enabled.
Files in Library folders are numerous and are often protected by multiple layers of security, many of which Hyperspace cannot bypass. Expect to see some scan errors related to this.
Furthermore, files in Library folders are frequently modified by running applications. If you enable this setting, it’s even more important to heed the advice given elsewhere in this documentation and run Hyperspace when no other applications are running.
By default, Library folders in home directories and at the top level of volumes are also ignored. This can be changed using the “Allow Library access” setting.

1.2.1 - April 7, 2025
Improved the resilience of purchase verification in adverse network conditions.
Q: Why does Hyperspace need additional permissions to scan the Documents and Desktop folders within iCloud Drive?

1.2 - April 3, 2025
Added support for cloud storage (e.g., iCloud Drive, OneDrive, etc.)
Added support for reclaiming files that are compressed at the file system level.
Improved performance when checking if two files are already clones of each other.
Fixed a bug that caused the progress bar to complete too early during reclamation.

Allow cloud storage access - When enabled, Hyperspace will be allowed to access files that are backed by cloud storage. Some common examples of cloud storage are iCloud Drive, Microsoft OneDrive, Google Drive, and some versions of Dropbox.
Learn more about how cloud storage is handled by Hyperspace.
Q: How does Hyperspace handle cloud storage?
A: By default, Hyperspace ignores files backed by cloud storage. To change this, enable “Allow cloud storage access” in Settings.
Files that are completely downloaded and up-to-date are treated just like any other local files when it comes to identifying duplicates and reclaiming storage space.
Q: What qualifies as “cloud storage”?
Q: Why does Hyperspace need additional permissions to scan the Documents and Desktop folders within iCloud Drive”?
(This permission is necessary to even attempt a scan. Individual file and folder permissions, ownership, and so on can still prevent specific items from being scanned.)
When the user selects the top level of iCloud Drive as a scan source, Hyperspace gains the ability to scan items within iCloud Drive. But the Documents and Desktop folders are not within
iCloud Drive. They’re in the user’s home directory. The existence of symlinks in iCloud Drive that point to the Documents and Desktop folders do not give Hyperspace permission to scan those locations.
Q: How does Hyperspace handle symbolic links?
A: Symbolic links (“symlinks”) are tiny files that point to another location in the file system (e.g., another file or a directory).
Hyperspace ignores symlinks.

Reclamation: The process of replacing a set of files that have identical contents with space-saving clones of each other, reclaiming disk space. When a file is “reclaimed” that means it is replaced with a space-saving clone.
Target file: In each group of identical files, one file in the group is designated as the source file and the rest are “target” files. The target files will be replaced with space-saving clones during reclamation.
General settings:
Restore folder dates - When enabled, folder modification dates will be restored to the values they had before reclamation began.
Advanced settings:
Applications (i.e., .app packages) are always ignored, regardless of the state of this setting.
Reclaim files inside packages - When enabled, the contents of package directories will be eligible for reclamation. This setting has no effect unless the “Scan inside packages” setting is enabled.
Applications (i.e., .app packages) are always ignored, regardless of the state of this setting.
Once Photos access has been granted in System Settings, the “Allow Photos access” setting within Hyperspace can be turned on or off as desired at any time.
As mentioned earlier, the green and red “+” and “-” buttons can be used to add and remove folders to scan. Multiple folders provide more files to scan, of course, but they also potentially allow more duplicates to be found.
Q: How does Hyperspace determine if two files are identical?
To determine if two files have identical contents, Hyperspace first compares the file sizes. If the files are not exactly the same size, down to the byte, then the files are not identical.

1.0.5 - March 9, 2025
Added a setting to restore folder modification dates after files are reclaimed.
Further improved heuristics for checking if file-system-compressed files are clones.
• Added missing source/target information to some error messages.
Q: Why am I asked to sign in to my Apple Account when purchasing Hyperspace?
Restore folder dates - When this setting is enabled, folder modification dates will be restored to the values they had before reclamation began.
The act of reclaiming a file will update the modification date of the folder that contains the file. This is an accurate reflection of what has happened: the folder was modified when one of the files it contains was replaced with a space-saving clone.
If you prefer that folders not reflect this modification, enable this setting and Hyperspace will reset folder modification dates to their pre-reclamation values.
