CopySkipper

Quick start

Drag your Source folder (left).
Drag your Target folder (right).
Click Sync now.
Optional: enable Auto-run to sync on an interval.

CopySkipper main window screenshot — Drop Source and Target folders, then press Sync now.

Note: CopySkipper performs a one-way sync from Source → Target. It does not merge changes both ways.

Options (what they mean)

Auto-run: runs sync automatically at the selected interval (for example every 5 minutes).
Mirror (delete extra items in the target folder): removes files that exist only in the Target. This is equivalent to using rsync with --delete. Use with care.
Play a sound when finished: plays a short completion sound.
Show a notification when finished: shows a macOS notification after sync completes.
Show log: opens the log panel so you can see what happened during the last run.

Troubleshooting

How do I cancel a running sync?

Click Cancel sync.

The progress looks stuck at 0%.

Deletions and metadata updates can move the progress bar slowly at first. The final completion state is accurate.

Auto-run doesn’t start immediately.

Auto-run triggers after a sync completes and the selected interval elapses.

Is this safe? Will it delete my files?

By default, CopySkipper copies Source → Target. Deletions happen only if you enable Mirror (rsync --delete). When in doubt, test with a small folder first.
