The program is easy to use, the search function is good, the output is excellent, it works well with all versions of Windows operating systems (even 32-bit ones), it's intuitive to learn how to use and it's very fast in finding duplicate files. I would like the program to be able to find duplicates within large directories or folders and not just small files. It does what it's supposed to do and I have no complaints about it. I am keeping track of file duplication on our computer's hard drive and this software has helped me keep my computer clean of unnecessary files.
