# Duplicate File Remover 3.7

Released on October 8, 2015

Duplicate File Remover is a powerful tool to locate file duplicates on your computer. 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.
