DoubleKiller searches single or multiple folders/partitions for identical files. Depending on the settings the files' names, sizes, dates and/or CRC32-checksums (which represent the content of the files) are compared with each other. Masks like *.mp*g or *.dll define which files are (not) scanned. Files with certain flags, e.g. hidden files, may be excluded from the search. Besides you can limit the search to files with a user-defined filesize. When the search is finished a list containing all double files found is displayed and you can select the files which should be deleted or moved.....(free).....
