DoubleKiller

DoubleKiller searches for duplicate files by comparing any combination of name, size, modification date, and content. You can exclude files or limit the scan to files matching masks like *.MP3, files in a particular file size range or files with certain attributes, like hidden or system files. When the scan is finished a list containing all duplicates found is displayed and you can manually or automatically select the files to be removed. The result list can be sorted and exported to a textfile readable by both humans and spreadsheet applications. DoubleKiller is a stand-alone executable that does not need to be installed, just extracted and run, and does not alter the system in any way without the user's prior permission.

Version 1.6.2 includes minor user interface improvements.
