The M75 file extension was reported to be used in one of the older versions of Apple QuickTime Player, Apple's multimedia player and media-handling software.
The available information does not establish the exact type of data stored in this file or describe a current standalone format. It should therefore be treated as a legacy QuickTime Player data file rather than as a generally supported media format.
QuickTime Player was available for Apple Mac OS X and macOS, as well as Microsoft Windows. The .m75 file format is old and is not generally used by current versions of the software.
Try opening the .m75 file with the version of QuickTime Player associated with it. QuickTime Player for Mac and QuickTime Player for Microsoft Windows are the relevant programs for this record.
Because the format was reported for an older version of QuickTime Player, a current installation may not recognize it. If it does not open, an older compatible QuickTime environment may be required.
If QuickTime Player can open the .m75 file, use its available export or save options to create a more commonly supported media file.
If QuickTime Player cannot recognize the file, conversion is not normally possible without first opening it in the compatible older software.
