This utility makes it simple to back up files from a selected PC folder to one or more external drives without creating duplicate files. It only copies over new files that have been added to the PC folder. This keeps your external backups clean and up to date.

• The program scans a selected folder on your PC.
• It then compares the contents of that PC folder to an external backup folder.
• On the first run, it creates a .txt file listing all files currently in the external folder.
  • On subsequent runs, instead of re-scanning the external folder (which can be slow with thousands of files), the utility simply reads from this file to get an instant snapshot of what's already backed up and then updates the .txt file at the end with any file changes.
• It then compares both file structures:
  • New files in the PC folder are copied over to the external folder.
  • If a file or folder is renamed on the PC, the utility will:
    • Copy the renamed item.
    • Move the old version on the external drive to a /Quarantine folder (for safe review and cleanup).
• This smart scanning approach reduces external drive reads, saving time and wear on your hardware.

✅ You no longer need to manually copy files to every external drive—just update your PC folder, and let the utility sync them all efficiently.
