remove duplicate filesOf all the files that clutter our hard drives and take up valuable disk space, none are more useless than duplicate files. They’re worse than useless – taking up extra space in our backups and cluttering our file lists.

Duplicate files come in a variety of flavors. In addition to exact copies of files, you may have very similar images, music files that contain the same song ripped from different sources, or text documents that are almost the same but contain a few lines of unique text. These tools will help you remove duplicate files to whip your file collection into shape and free up valuable disk space.

dupeGuru

dupeGuru is an easy-to-use tool for finding duplicate files. It can check for duplicate files based on their file names or contents. Its “fuzzy matching algorithm” allows it to detect duplicate files when their file names or contents are similar, but not exactly the same.

dupeGuru is very simple to use – add one or more folders, click Scan, and it will tell you which files are duplicates. You can delete the files from within dupeGuru. While you can try dupeGuru for free, you’ll have to buy it if you want to delete more than ten files at a time.

WinMerge

WinMerge isn’t like other duplicate file-finding tools. It’s focused on locating and merging similar files. For example, you may have multiple copies of a text document, each with a few different lines. Maybe you edited them both and you aren’t sure which is the latest copy. Maybe each contains important information. If you don’t want to lose anything, WinMerge will give you a side-by-side look at the differences between the files and allow you to merge them.

When you use WinMerge, you choose a “left” folder and a “right” folder to compare.
