Hmmm... Since it is not possible to remove a file name of a saved Windows Movie Maker project altogether (leaving it blank) I have to assume you want to rename it instead? Are you asking how to 'rename' a file? If so, right-click the file and choose Rename from the drop-down menu.
A Windows Movie Maker project file is in .MSWMMformat.
A Windows Movie Maker project file is in .MSWMMformat.
You can't index a file for Windows Movie Maker.
You can't do that on Windows Live Movie Maker, but you can extract the audio from a video in Windows Movie Maker v2.6 and save/publish it as an audio file.
There are three ways to install Windows Movie Maker 2.1 for Windows XP on Windows 7.1-First on Windows XP go to programs on C drive and copy the Movie Maker program file and paste it into your My Documents or Downloads folder. A copy of the Movie Maker program file should now be in your my Documents or Downloads folder where you have pasted it.Go to where you have pasted the Movie Maker file,right click on the file with your mouse and click send to zip folder. This creates a zip file with all the Movie Maker program files inside. Now to install Movie Maker 2.1 on Windows 7 you can either-1-Transfer the Movie Maker zip file from your Windows XP computer to your Windows 7 computer using Microsoft shared View or Team Viewer.Which lets you transfer files from one computer to the other computer.

Or-3-Transfer the Movie Maker zip file onto a USB thumb drive from your Windows XP computer and install it onto your Windows 7 computer that way.Once you have got the Movie Maker zip file onto your Windows 7 computer using one of the three methods above. Open the zip file and extract the files to Programs on C drive and make a new folder. Rename new folder Movie Maker 2.1 so that it does not conflict with any other versions of Movie Maker you have installed.Now send the Movie Maker short cut to your desktop and click on it.

And the web cam feature will also work.But please note, you must have Windows Movie Maker 2.6 installed in order for Windows Movie Maker 2.1 to work.

But as long as you have Windows Movie Maker 2.6 installed,then Windows Movie Maker 2.1 will work on Windows 7.Windows Movie Maker 2.1 works on Windows 7 without any problems.

A Windows Movie Maker project file (MSWMM) can only be edited/viewed in the Windows Movie Maker program.A Windows Movie Maker movie/video file is the Finished/Published version of the project file which has been converted to a finished Standard Format for viewing.
Most likely because that file type is not supported in Windows Movie Maker
You can't play unsupported file extensions in Windows Movie Maker. You have to convert the file to a format compatible with the program.
You have to Publish the video first (that is exporting). The process changes the Windows Movie Maker file to a Standard viewing format (and not a project file).
.MSWMM
That is not a file format. Undf stands for 'undefined file'. Files used in Windows Movie Maker have to be compatible with the program as well.
