Duplicate File Finder

This is strange, because I've just connected an external drive. It shows up normally on the Duplicate Finder and scanning and detection of duplicates works fine on the external drive, too.

When you open the Duplicate Finder, just press Browse and select the drive(s) / folders you want to scan.

Hello Steve,

Please be informed that AVG Duplicate Finder can only list out the HDD on your PC and not the external hard drive that are connected.
Feel free to contact us for further queries.

Can AVG duplicate file finder be used on an external hard drive?  If so, how?
