The requested operation cannot be performed on a file with a user-mapped section open

Question

Whenever I tried to copy 4 files into my bin folder, after stopping the main service, I am getting an error with one file (TexteDll). The error is:

Cannot co         


        

Answer 1

Others have already established that this error is due to another application having a lock on the file. Just wanted to point out that git diff locks files as well until you quit out of it. That's what caused this in my case.
