Duplicate File Finder (and we should add, deleter) is a freeware application developed by Auslogics and certainly one of the best freeware system cleaning applications featured on this site.
Duplicate File Finder completes tasks which might otherwise take hours to complete were one doing them by hand with Windows Explorer. The idea of this program is while downloaded files on a system build up overtime, it's possible duplicate files get moved around from folder to folder and you end up with multiple copies hogging up disk space. Running this program will solve the problem of copies taking up space.
Duplicate File Finder is licensed as Freeware for Windows (32-bit and 64-bit) operating system / platform from system cleaning software without restrictions. Duplicate File Finder 6.1.4 is available to all software users as a free download (Freeware).
Compatibility with this duplicate finder software may vary, but will generally run fine under Microsoft Windows 10, 8, 8.1, 7, Vista and XP on either a 32-bit or 64-bit setup. A separate x64 version may be available from Auslogics Software Pty Ltd.
