MSWMM is an acronym for Microsoft Windows Movie Maker. Files that contain the .mswmm file extension usually hold project files that contain pointers to various media files that have been created with the Microsoft Windows Movie Maker software.
The Microsoft Windows Movie Maker software allows a user to create, edit and share movies that they may make at home using either a digital or analog video recorder. The MSWMM file does not contain any actual media content. It only contains the location of the actual media files that the MSWMM file references.
Oftentimes users prefer to change an MSWMM file into another file format since the MSWMM file format is limited in its versatility.
