TwinSeek helps you find those duplicate files taking up space on your computer, although it doesn't take the extra step of removing them. The program's simple, clean interface makes it easy to choose a directory and search for duplicates or select two files and do a more extensive comparison. Search results for a directory scan are sorted by the percentage of similarities.
TwinSeek can only find duplicates and compare files of the same type, so a Microsoft Word doc and text file with the same name aren't considered matches. TwinSeek doesn't allow you to delete or move potential duplicates, unlike features found in some other freeware duplicate-file finders. While it won't get rid of those pesky duplicate files, TwinSeek can help you locate them and decide which ones to keep and which ones to toss.
