CyberLink P2I

CyberLink Power2Go software can create disc images of data/video discs and uses the extension P2I.

File Information
P2I files don't actually contain the disc image data, but stores information about the disc. The image data is stored in a sequence of files starting with .C00, then segmented ever 1GB sequentially. The .C00 file is an ISO and can be renamed, unless segmented then the files need to be concatenated. Also stored with the set is a RIF file or "Recording Image File" with additional information about the disc image.
