There is only one file type that uses the .MVM extension:
Photostory Deluxe Slideshow
Slideshow created by Photostory Deluxe, an application used to create presentations; contains the editing steps and links to the original files that appear in the slideshow.
MVM slideshow files are automatically saved when the associated .MPH project file is saved. MVM files are useful because you can export them to transfer to other projects.
To create a slideshow to transfer to another project, select.
