What is the difference between .pgx and .art?

Description: The PGX file format is associated with Hopedot VOS, a virtual operating system software that allows users to run a separate operating environment on their computers, similar to virtualization technologies. A PGX file typically contains data related to the Hopedot VOS environment, such as settings, applications, and other user-specific information.; PFS Art Publisher Image (ART) is a raster graphics file format used for storing digital images. It was developed by Progressive Networks for use in their Progressive FreeStyle Art Publisher software. ART files are compressed using the run-length encoding (RLE) algorithm, which allows them to store large images in a relatively small file size. The ART format supports up to 24-bit color and is often used for storing digital photos and other images.
