Download Duplicate File Finder
The name of Duplicate File Finder pretty much tells the story. The app helps you locate, organize and potentially eliminate duplicate files on your system. You choose a set of search criteria to match your needs for the duplicate search and Duplicate File Finder provides a results list. Compare files by name, size, extension, location and file contents. If you're doing an image search, the results pane also includes a thumbnail for quick comparison so you can see if IMG_0012.jpg is really the same photo as MomsBirthday2006.jpg without opening the images. If you simply want a catalog of duplicates, the software outputs results as text, csv and HTML. In general, I'm still partial to DupKiller, but this is a great alternative. [Windows 9x/2k/XP $0.00]
