This utility finds true duplicates (byte for byte check)! CIF doesn't use the unreliable CRC check.

CIF is able to check your drives for annoying duplicate files, and provides easy capability of deleting them, saving you megabytes of precious diskspace. Features include added multiple folders and subfolders easily for scanning, show file info under cursor, select identical files manually, by directory or by pattern, automatically leave at least one original. All in all, this software can be considered an absolute must-have for people who have huge collections of files, pictures or mp3.
