From Big Bang enterprises:
DoubleKiller Pro finds duplicate or similar files by comparing any combination of name, size, date and content; optionally just a certain part or with a given tolerance. Files can be filtered by masks like *.dll, attributes or file size. When the scan is finished a list containing all duplicates found is displayed and you can select the files to be deleted, moved to the Recycle Bin or a backup folder or replaced by shortcuts. Automatic selection allows to mark the oldest or biggest files of each set for removal. The complete process of choosing directories, scanning for duplicates and removing files can be automated via command line switches. The user interface is multilingual and can be translated to your language using freely downloadable language files. An optional help file provides first-step information, a complete reference and usage examples. DoubleKiller Pro 2.1 adds support for scanning inside zip archives and allows to cataloguize CDs/DVDs/folders and scan the catalogs.
