What CloneSpy is
CloneSpy is a free Windows utility for finding and removing duplicate files to help reclaim hard drive space. It can scan local folders and hard drives, DVDs, network drives, and checksum files. Matching options include identical contents, filenames, titles, extensions, similar sizes, and zero-byte status. Users can preview files, use automatic selection, exclude folders, and send removed files 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. Its comparison is binary rather than content-based, so differing metadata may keep apparently unchanged documents from being treated as equal.
