SSF

SSF is a program that helps to find duplicate or similar files. In the process of working, a large number of versions of the same files are discovered. The SSF tool finds them, even if they are in the most remote and rarely visited parts of your hard drive. The degrees of similarity can vary from simple name equality to complete overlapping of file contents. Similar files found are displayed in two lists. The source file group is at the top of the list, and the target file group is at the bottom right of the list.
Files from both lists can be sorted by any column.
You can set the display of the relationship between the lists. In this case, when you select a file in the source group list, in the target list only files similar to it according to the selected similarity criteria will be displayed and selected.
