DoubleKiller Pro

DoubleKiller Pro searches for duplicate files in specified folders, displays a list of them and allows further work with them, such as deleting them, moving them to another folder or putting them in the system recycle bin. Duplicates can be sorted by file size, date, folder location or CRC32 checksum. Files can be compared either by complete content, or by size, CRC32, or by a complete byte match. Specific files can be omitted from the search (e.g. .dll, .sys, .inf, etc.) and .zip archives can also be searched.
