The only files that show up in PDBs are source files for the resulting objects (e.g., .c); there are .exp and other files in that tree.

Actually, static and dynamic libs also show up, as do resource files. So I guessed that .obj is .c (not always accurate), .res is .rc, and dynamic .lib is .exp, and so on and so forth.
