The .pxc file extension is most commonly associated with the Photodex ProShow slideshow creation software. Photodex ProShow is used to create slideshow presentations from digital photos. The PXC files contain cache files that store metadata about the contents of a Photodex ProShow slideshow, such as the video, audio and image information. These files allow the application to load the PSH slideshow files more quickly.
The .pxc file extension is also used for MatrikonOPC server configuration files and PX-Edit classifications files.
