DoubleKiller searches single or multiple directories for duplicate files by comparing any combination of file name, size, modification date and content. Using user-defined masks like *.mp3 or *.dll you can limit the scan to files that interest you or protect important files from being scanned. Furthermore you can exclude files in a particular file size range or files with certain attributes, like hidden or system files.
