CloneSpy 3.32 (x86/x64) + Portable | 4.4/6.2 Mb
CloneSpy can help you free up hard drive space by detecting and removing duplicate files. Duplicate files have exactly the same contents regardless of their name, date, time and location. Also, CloneSpy is able to find files that are not exactly identical, but have the same file name. Perhaps you have different versions of a file and you want to find all of them and remove the older versions. CloneSpy can also find zero length files. These are files that have no content.
