Movie File Merger (MFM) helps you with the selective combination and cleanup of video collections, like home videos, movies, series, or documentaries. It can be used also for other types of collections, like music, or basically any files, but MFM is optimized for videos. MFM is portable, so that you can run it from anywhere, on any hard disk or memory stick, or even in Dropbox, which makes it easier to share lists with other people.
