What is a MSWMM file?
Developed by Microsoft, the Windows Movie Maker saves its output in the MSWMM file format. The file format is similar to the WLMP format, which was used by the previous generations of the software. Windows Media Maker allows the users to save raw, unfinished work in this format, and you can edit the same to make the necessary changes.
You can export the finished work in a DVD or any other standard video format such as AVI.
