Duplicate File Remover is a powerful tool to locate file duplicates on your computer (dedupe). It scans the computer and lists duplicate files based on Byte for Byte Comparison, which ensures 100% accuracy. It can find duplicates of any files: text, binary, music, video or images. For multimedia files (MP3, OGG/Vorbis, WMA), the contents of the following tags can also be analyzed: "Artist", "Album", "Title" and "Comment". The file Summary property can also be searched: title, subject, category, and author. Duplicate files can be deleted, hard-linked, moved, or copied. The list of duplicate files can be sorted, exported to an HTML report, and acted upon.

You may not realize how many duplicate files you have on your computer, after numerous downloads from the Internet, or scattered over your home or corporate network. Duplicate files are in most cases redundant and unnecessary, so keeping them is merely a waste of hard disk space. Your hard drives may be full of extra copies of documents, MP3s, photos and videos waiting to be removed. Duplicate File Remover will help you reclaim valuable disk space and improve data efficiency.
