If duplicate files are your resident pest, then DoubleKiller is your exterminator. This free program from Big Bang Enterprises (we're not making this stuff up!) will scan your computer or selected directory for duplicate files and allow you to easily remove them from your system.

If permanently deleting files makes your neck sweat, not to worry: DoubleKiller protects you from any mistaken or dumb deletions. First of all, DoubleKiller ensures the accuracy of duplicate files by checking the name, size, date, and CRC32-checksum of your files. You can also limit scans to particular masks and exclude files matching certain masks (by default, DoubleKiller excludes any .dll, .sys, .vxd, and .inf files).

Simple to use and easy to customize (not to mention free!), DoubleKiller is the ideal program to do your duplicate dirty work. Windows only.
