What is a .f4v file?
A .f4v file is an MPEG-4 video. Its registered MIME type is video/mp4, which places it in the video family of formats.
F4V is a binary format: the contents are not readable text, so opening it in a text editor shows scrambled characters.
The same format is also saved with the extensions .lrf, .lrv, .m4v, .mp4, .mp4v, .mpg4.
