Undo & Redo

Media Sort records every sorting action (moves, copies, renames, and deletions) in a history stack, allowing you to undo mistakes instantly and redo actions you change your mind about.

What Can Be Undone

The following actions are reversible:

Move: the file is moved back to its original location
Copy: the copied file is deleted from the destination
Rename: the file is renamed back to its original name
Delete: the file is restored from the system trash to its original location

How Deletions Work

When you delete a file (by pressing Down), it is not permanently removed from disk. Instead, it is moved to your operating system’s native trash facility:

Windows: Windows Recycle Bin (via native shell API)
macOS: Trash folder (via Cocoa NSFileManager)
Linux: Desktop Trash (Freedesktop.org trash specification)

Because the file remains in the system trash, undoing a deletion programmatically restores it to its exact original path.

History Lifecycle

While the app is running, all actions remain in the undo/redo stack and can be reversed at any time. There is no fixed limit on history depth.
When you exit the app, the history stack is cleared. Any delete actions that were in the undo stack are finalized. You can no longer undo them through Media Sort.
After exit, deleted files still exist in your system trash and can be manually restored using your operating system’s file manager.

Limitations

Actions that involved files which were later modified or moved outside of Media Sort may fail to undo correctly. In such cases the action is skipped and a notification is shown.
File system watcher events (files added, modified, or deleted by external programs) are not tracked in the undo history.
