What is a MOOV file?
Legacy QuickTime movie format (now migrated to MOV)
The MOOV movie file format is used to save compressed movies in a multimedia format that was originally created by Apple. The MOOV file format was originally the default Macintosh extension with MOV files used for Windows Quicktime. Now, you’ll often see .mov files instead of .moov files because Apple has decided to migrate the MOOV file over to MOV for better cross platform consistency for Quicktime Movie Files.
