This article explains the different file formats that use the PTX file extension. It also explains how to open each type, and how to convert your file to a different file format.

Some PTX files are Pro Tools session files used to reference audio files. Previous versions of the software (v7–9) use PTF files for the same purpose, while v6 and earlier append PTS to the end of the filename.
If the file is not in that format, it may instead be an electronic transcript file. These are often used to store transcripts of court hearings and may be in this format or in a standalone EXE file. The former is normally used so that the file can be sent via email (EXE files are usually blocked by email servers).
PaintShop Pro also uses this file extension for images used as textures for objects and shapes. Some other uses include Pentax RAW images, PopCap Games video game textures, and V.Flash PTX raster images.
