What STL and PLY files are

STL

STL is the standard file format for 3D printing. It describes a model's surface as a mesh of triangles without colour, texture or units, which keeps it simple and universally supported by slicers and CAD software.

PLY

PLY (Polygon File Format, also known as the Stanford Triangle Format) was created at Stanford University in the 1990s to store data from 3D scanners. Besides vertices and faces it can hold per-vertex colors, normals and other values in text or binary form, which makes it popular for 3D scans and point clouds.
