File extension PTX (.PTX) information

If Windows is unable to open PTX files you may not have the appropriate program installed or may have a registry related error. We strongly recommend that you run a free registry scan.

Appropriate program:

The .PTX file extension identifies Pentax's RAW bitmap graphic files. This is a RAW "raster" image file format which saves the image as stored by the camera, without compression or processing, and which can be viewed using Pentax's own software.. Incorrect associations are the cause of many file extension errors. Scan your system to prevent and identify association errors.

• Performance: To optimize memory and CPU usage for PTX files run a free performance scan.
• Stability: Fix PTX errors to make your system and applications more stable.
• Drivers: Scan your PC for the outdated drivers which lead to system errors and slowdowns.
