Duplicate & Same Files Searcher
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 (C:\Users\MyName), to examine files of a particular type (*.mp3, *.jpg), to ignore others (*.iso, *.exe), to check only files of a defined size.
