Download.com Staff Feb 27, 2009
Despite its demo limitation, this handy application effectively finds duplicate, space-hogging files in your hard disk. DoubleKiller Pro's tabbed interface looks rather boring and confusing because of the number of buttons and options. The program lets you select the folder you want to scan, and specify which type of duplicate files to exclude or include. In our tests, the speedy application scanned our entire 20GB hard drive in only a few minutes. DoubleKiller Pro generates a color-coded list of duplicate files, including information such as filename, path, and date of creation. Right-clicking an item allows you to run the file, open its mother directory, and copy and export the entries. However, deleting duplicates is restricted in the demo. Still, DoubleKiller Pro proves to be effective and we recommend it for users who have bloated hard drives.

Developer's Description

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.
