Typical Filename: VSPreclean.exe (or sometimes distributed as a script/add-in).
The .exe extension indicates that this is an executable file. The name suggests it might be related to cleaning up or preparing some environment within Visual Studio.
Projects with custom pre-build events that invoke tools (e.g., copy, xcopy, or file transformers) might not release file handles properly before VS’s clean step runs.
During a failed or cancelled build, files like .obj, .pdb, or .tlog remain locked by a lingering mspdbsrv.exe or cl.exe. When you run a clean build, the pre-clean step fails with “exclusive access denied”. vsprecleanvsexe visual studio 2012 exclusive
