How to fix the issue when Windows Movie Maker cannot save the file to the specified location?

Sometimes you can face this error trying to use an inappropriate video file format. In this case, the solution can be found by converting your file to WMV. Also, the source file and saving location must be available when you trying to export a video.

However, this troubleshooting can be related to other things. For this sake, you have to manipulate with Tools → Options menu. You should disable all the filters that you can see on the third tab. Then shut down this window and try to save your movie.

Verify that the original source files used in your movie are still available, that the saving location is still available, and that there is enough free disk space available, and then try again.
