If you have ever worked with Windows Movie Maker 2011 or 2012, you may have run into a situation where you're working on a project where it's partially done, but you need to build a Project to another location, on another PC and be able to work on that video project there as well.
Windows Movie Maker provides some baseline video editing abilities, but one of the things that it does not do is consolidate all of the media that are being used in the composition/rendering of the video. About two months ago, I was in the Windows Movie Maker support forums and there was an individual who is requesting for Windows Movie Maker to be able to grab all the media that was being used for his video composition and consolidate all media types into one folder.
Unfortunately, Windows Movie Maker 2012 doesn't do that. When you're working with a video project in Windows Movie Maker, Windows Movie Maker simply looks to the location where the source video is and works from there.
