Undo / Operation History

Press Cmd+Z (macOS) or Ctrl+Z (Linux) to undo the last operation.

Supported Operations

Operation	Undo Action	Backend Support
Delete	Restore from trash	Local only
Rename	Rename back to original name	Local only

How It Works

Delete Undo (macOS)

• Uses NSFileManager.trashItemAtURL to move files to trash
• Records the resulting trash URL for each file
• Undo moves files from trash back to their original locations

Delete Undo (Linux)

• Uses the trash crate to move files to the freedesktop trash
• Undo support is limited on Linux

Rename Undo

• Records original path and new name
• Undo calls renameFile(newPath, originalName) to reverse the operation

Toast Notification

• After each operation, a toast appears above the function bar
• Shows operation summary (e.g., "Deleted 3 file(s)")
• "Undo" button appears only for local backend operations
• Auto-dismisses after 8 seconds
• Click "Undo" or press Cmd+Z to reverse

Limitations

• Maximum 20 operations in history (in-memory only, not persisted)
• S3 and SFTP deletions cannot be undone (no trash concept)
• Move operations are not currently undoable
• History is cleared when the app is closed
