3. The Location of your Duplicate Files

Duplicate Sweeper can remove duplicate files from your computer hard drive, attached external drives, network drives, Google Drive, OneDrive and iCloud Drive.

Removing duplicates from an External or Network drive

Please note that Duplicate Sweeper will not remove duplicates from external/network drives if the removal location is set to the Recycle Bin within Duplicate Sweeper's Preferences.

Go to Edit > Preferences > Removing Duplicates in Duplicate Sweeper and choose a location on the drive the files are being searched on.

When removing duplicates, the removed files will then be moved to the chosen folder on the drive. You can then either manually delete the folder containing the removed files, or recover any files should you wish.
