What is a PSO file?

PSO files mostly belong to DirectX Shader Compiler. PSO files serve several roles. The most common type is a compiled shader file made by tools like the DirectX Shader Compiler. These files hold binary code used by the graphics pipeline to process pixel shading for real‐time rendering.
Some PSO files come from Phantasy Star Online where they store game characters or state information.
Other files with this extension are linked with Adobe Photoshop environments. In these cases, they may contain preferences, custom shapes, or even data from Particle Swarm Optimization routines used for optimization tasks.
Key types include:

Compiled shader objects: Used in games and graphics applications. (DirectX Shader Compiler)

Game data files: Holding save or character data from titles like Phantasy Star Online.

Settings and optimization files: Associated with Photoshop and related processes.

FilExt.com notes: Choose the proper application to open a PSO file. A developer tool or shader viewer will work for shader files. For game data, use the relevant game software, and for Photoshop settings, open the file with Adobe Photoshop.
