CloneScan

Duplicate & Same Files Searcher is an advanced tool for locating and dealing with duplicate files. The program locates files with identical content only; unlike some similar tools, you can't compare files just on their names, dates or size. This makes Duplicate & Same Files Searcher relatively slow, as it must read and process every single file in your selected group. Fortunately, there are some ways to improve performance. You can direct the program to scan a particular folder tree only, to examine files of a particular type, to ignore others, to check only files of a defined size. There are some options you won't often see elsewhere. You can have the program check for (or ignore) differences in alternate data streams, to ignore different ID3 tags in MP3s, to skip symbolic links (or not). When the scan is complete, each set of duplicates is listed, along with their file names, paths, size, dates, even their number of fragments (whether they're fragmented or not).
