Files with the .PRPROJ extension contains video project data consisting of the video and audio time line and its superimposed data, namely transitions, special effects, and other editing elements, as well as project, rendering, video and audio format, and recording format settings.

Project files do not directly store the video, audio, and graphic data, but only references to them, saved during the import, which is why users should pay attention to situations where files need to be transferred. PRPROJ files are characteristic for the professional video editing software Adobe Premiere Pro. It is used to create feature films, broadcasts, and video presentations. Adobe Premiere Pro is part of the Creative Cloud suite, a service that provides access to various Adobe software and tools for designers to create and collaborate.
