A PRT file contains portal information used by the Valve Visible Information Set (VVIS) command-line tool included with Hammer Editor, which is a program used to build maps for Valve games such as Half-Life. It stores a list of portals in ASCII format that are used by VVIS to perform visibility calculations to determine which objects on a map can be seen by a player and must be rendered.

A PRT file may also be a model part file saved in a three-dimensional model format used by Unigraphics, a 3D CAD program. It contains surface and solid information for a single part. PRT files are saved in a binary format, similar to an Alias wire model and an SDRC (Structural Dynamics Research Corporation) model.

3D model created with Solid Edge, a CAD program used primarily for creating industrial parts and assemblies; can be combined with other 3D parts in an assembly (.ASM) file.

Contains configuration information that allows the computer to communicate with the printer; may be used by certain software programs, such as Dr. Halo software, which saves images in a device-independent format.

Output from a printing job sent to the printer and saved as a file; contains formatting information that tells the printer how the document should be printed.
