When preparing Duplicate Cleaner for scanning your drive, you can have it examine or ignore file content. You can tell it to consider files with the same name, with similar names, or to ignore names completely. It can also match files by the Created and Modified Dates. A special Audio Mode tab helps you find duplicates of the same song by title, artist, and other such data.
If your hard drive is so overloaded that you hesitate to install even a 5MB program like Duplicate Cleaner Free, go with this old but still workable version of Easy Duplicate Finder. It's portable. You can download it on one computer, put it onto a flash drive, insert the flash drive into your PC, and run it without putting anything on the hard drive. It's not the current version of Easy Duplicate Finder
