CloneSpy
What it is
CloneSpy is a free Windows utility for finding and removing duplicate files to reclaim hard drive space. It can search local folders and hard drives, DVDs, network drives, and checksum files. Matching options include identical contents, filenames or titles, extensions, similar sizes, and zero-byte files. You can preview files, use automatic selection, exclude folders, and send removed items to the Recycle Bin. CloneSpy can delete or move redundant files, export a list, defer operations to a batch file, or replace duplicates with shortcuts or NTFS hard links. It can create checksum files from DVDs or hard drives and use them to check whether files already exist on the system. The installer offers standard and portable installation, and portable files can be copied to other computers. Version 3.43 is listed as the latest version, dated 12.10.2019. The FAQ says its comparison is binary rather than content-based, so metadata differences can mean apparently unchanged documents are not treated as equal. The FAQ also says it does not identify visually similar images or songs with differing files.
