About PSK
Epic's ActorX plugin exported Unreal Engine's skinned meshes as PSK and their animations as PSA, and UE Viewer, also called UModel, saves Unreal Engine games' models the same way, so modders pass them around and bring them into Blender. A PSKX holds a static mesh, or more vertices than a PSK allows.
Both are a run of chunks, each a name, a size and a count. A PSK keeps its points, its wedges with their skin coordinates, its faces, its materials and its skeleton with each vertex's weights. A PSA keeps the same bones and its sequences, each with a key for every bone in every frame.
Filepeek draws the mesh posed on its skeleton, each material with the picture its .mat file or its name points to among the files dropped with it, and plays a PSA's sequences on it when they're dropped together. A PSA on its own plays on its bones alone, like a motion capture take.

Questions
How do I see a PSA's animations on its model?
Drop the PSA together with the PSK. Each sequence becomes a take on the player under the model.
Where does a PSK take its textures?
From the pictures its materials name, which UE Viewer saves beside it, with a .mat file for each material naming its textures. Drop them together with the PSK.
Can I save it as another format?
Yes. Choose Export to save it as GLB, OBJ, STL or USDZ, or the view as PNG.
