File type: Various data file
A UVU file contains video data used by Windows Movie Maker, Microsoft's video-editing software for Windows.
File type category:
Various data file
Date updated: October 6, 2026
The uvu file extension is associated with Windows Movie Maker, a video-editing application developed by Microsoft for Microsoft Windows.
A UVU file stores video data used by Movie Maker. It is an application-specific data file rather than a general-purpose video file intended for playback in media players.
Windows Movie Maker is discontinued, so UVU files may be difficult to use on current Windows systems.
MIME types:
video/vnd.dece.mp4
Open a UVU file with Windows Movie Maker on Microsoft Windows. The file may require the Movie Maker project or editing environment that created it, and it is not expected to open directly in ordinary media players.
Because Windows Movie Maker is discontinued, there may be no supported modern application that can open this file if the original software is unavailable.
A UVU file is not a general-purpose video format and normally cannot be converted independently with a standard media converter. If Windows Movie Maker can open the file and its associated project, use the application's movie-export or publishing function to create a video in a supported output format.
