It is important to mention that Primavera P3 was originally developed by Primavera Systems, which was acquired by Oracle. The P3 software, originally released in 1994, was discontinued on December 31, 2010, therefore both the software and the PRX format are obsolete.

Windows Media

For Microsoft Windows and Windows Media multimedia programs, the PRX file is an XML file used to publish digital video files.

The PRX stores the audio and video codecs to be used, as well as the bit rates and the target language.

Note that the PRX is not a video file, therefore it is not considered a multimedia file.

Open a PRX file

PRX files are referenced (and therefore can be opened) by various Microsoft Windows programs, including Windows Media Player, Windows Media Encoder, and Windows Live Movie Maker.

Edit a PRX file

PRX files can be edited using the Windows Media Profile Editor, which is included with the Windows Media Encoder installation.
