SPSM files mostly belong to Substance Painter. Substance Painter material file (SPSM): An SPSM file holds material data used in Substance Painter. It uses the HDF5 file format to organize information in a hierarchical way. This file stores settings and texture data such as base color, roughness, and normal maps.
Key details as outlined by FilExt.com include:

Structured material properties

Texture references for 3D models

Efficient data storage using HDF5

FilExt.com tip: You should open these files with Substance Painter to view or edit the material details. An HDF5 viewer may show the raw data, but it will not display the material effects properly.
