A file with the PTX file extension might be a Pro Tools Session file that's used to reference audio files. Earlier versions of Pro Tools, versions 7 through 9, use the PTF format for the same purpose.

Your PTX file may instead be an E-Transcript file. These files are often used to store courtroom hearing transcripts, and can be in either the PTX format or in a self-contained EXE file; the former is normally used so that the file can be sent over email (EXE files are usually blocked by email servers).

PaintShop Pro Texture files use the .PTX file extension too. These are images used as textures for objects and shapes in PaintShop Pro.

Another file format that uses the PTX extension is the Pentax RAW Image format. These are uncompressed, unprocessed, raw image files taken with a Pentax digital camera.

How To Open a PTX File

PTX files that are Pro Tools Session files open with Avid Pro Tools.

When in the PTX format, E-Transcript files can be opened with E-Transcript Manager or for free, though in read-only mode, with E-Transcript Viewer. Since they're probably text-only files, you might also find a text editor like Notepad++ useful in reading the PTX file.

If a PTX file is a Paint Shop Pro Texture file, Corel PaintShop can be used to open it.

Pentax RAW Image files normally use the .PEF file extension, but those in the .PTX format can be opened with Windows Photos, UFRaw, and the software that's included with a Pentax camera.

Note: If none of these programs will open your file, it's possible you're just misreading the file extension. Some files look like they're PTX files because their file extensions are similar, but they might instead be PCX, PTG (PowerTeacher Gradebook Configuration), PTM (MapPoint Map), or PTB (Power Tab) files.

If you find that an application on your PC does try to open the PTX file but it's the wrong application or if you would rather have another installed program open PTX files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert a PTX File

A Pro Tools Session PTX file can be converted to the older PTF format using the Pro Tools software, but doing so will remove any features that are only supported in the newer PTX format. This can be done through the File > Save Session Copy menu.

Note: Remember that Pro Tools Session files are not actually audio files; just references to the audio files used with Pro Tools. This means you can't directly convert PTX to MP3 or any other audio format.

If an E-Transcript file or Paint Shop Pro Texture file that's in the PTX format can be converted to another format, it's likely done through the respective software mentioned above.

The free version of NCH Software's Pixillion image converter should be able to convert Pentax RAW Image files that use the PTX format.
