Open PRA File
The PRA format and extension files are a profile created with the Microsoft plug-in for Adobe Premiere, specifically version 6.5, which is used to export Premiere projects to Windows Media 9.
Adobe Premiere is a timeline-based video editing application developed by Adobe Inc. and released as part of the Adobe Creative Cloud licensing program.
PRA files are basically text files that contain the exported project settings for the selected Adobe Premiere project, such as the video codec, metadata, and the output file format.
PRA files are used to save and load Windows Media 9 plug-in settings within Adobe Premiere 6.5, which is why PRA files are saved in the Premier 6.5 plug-in directory.
