Can I undo a clean after RJL System Cleaner has deleted files?

There are two ways to recover from a clean:

System Restore -- If the System Restore point feature is enabled (it is on by default), you can use Windows System Restore to roll back your system to the state it was in before the clean. This restores system files and settings but may not recover all personal files.

Recycle Bin -- If you enable "Move to Recycle Bin instead of permanent delete" in Settings, all cleaned files are moved to your Windows Recycle Bin instead of being permanently deleted. You can open the Recycle Bin and restore any files you need. This option is off by default.

If both options are disabled, deleted files are permanently removed and cannot be recovered through normal means. This is why we show you every file with a safety rating before cleaning -- review the results carefully before clicking Clean.

For maximum safety, keep the System Restore feature on and consider enabling the Recycle Bin option until you are comfortable with how the app works.
