The m15 file extension is associated with Microsoft Money, a personal finance management software, developed by Microsoft Corporation. As of 2010, the product is officially discontinued and no longer supported by Microsoft.
The .mn1 to .m16 files are created when you install a new version of Microsoft Money. As part of the conversion process, it creates a backup copy of your unconverted file.
The file uses the relevant extension to the version it was last used in.
These files are not required for Money to run, but you should be sure you will never revert to an older version of Money again before you delete them.
Only these files can be opened in the previous version of Money, not the mny.

Apple QuickTime files are digital video files associated with Apple's QuickTime multimedia software. An M15 file can contain movie data, including video and potentially accompanying audio, for playback in QuickTime Player.
The format belongs to the legacy QuickTime software ecosystem. QuickTime Player was available for Mac OS X and macOS, as well as Microsoft Windows, but QuickTime for Windows is no longer supported. The M15 extension is therefore uncommon on current systems.
On a Mac, try opening the M15 file with QuickTime Player. On Windows, the file may open with the Windows version of QuickTime Player if it is installed and the required media components are available.
QuickTime for Windows is discontinued and unsupported. If a current player does not recognize the file, an older QuickTime installation or a compatible video application may be required.
If QuickTime Player for Mac opens the file, use its export or save options to create a movie in a more widely supported format. The available options depend on the media stored in the file.
If QuickTime Player cannot open the M15 file, conversion may not be possible without software that supports this legacy QuickTime file. Renaming the extension alone does not convert the movie.
