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 or updated files that have been added to the PC folder. This keeps your external backups clean and up to date.
Note
The selected or typed PC folder must match the external folder name or it will not run. For example, if you select or type C:\Users\johndoe\Pictures on your PC, the external folder must end with Pictures.
- 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
.txtfile 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
.txtfile at the end with any file changes.

- It then compares both file structures:
- New files or Updated 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
/Quarantinefolder (for safe review and cleanup).
- This smart scanning approach reduces external drive reads, saving time and wear on your hardware.
- Finally, a log file is created on the external drive detailing any changes made.
Tip
If you want to skip any subfolder inside the selected folder on your PC and external drives, simply select or type the name of the subfolder in the field under (Optional) Please add or select the folders from inside the selected PC folder to excluded from backup and then click the button Add Excluded Folder.
Note
When skipping a subfolder, any subfolder with either that name or part of that name will be skipped. For example, if you want to skip the MyExample subfolder, MyExample1, MyExample2, MyExample3 will all be skipped as they match part of the name MyExample. If you would like to change this, you can in the GetAllDirectories function.
✅ 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.
