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

Question

Problem :

Whenever I want to copy my 4 files into the bin folder, when I stop the main service, I always face an error with the one particular file (e.g. TexteDll). The error is as follows :

Cannot copy TexteDll: The requested operation cannot be performed on a file with a user-mapped section open

I guess it is happening may be due to some system locking. Or may be another process is using that DLL.

Can someone suggest a cause or solution for this ?.

It was observed in the past that the git diff locks the files as well until you quit out of git

And that will not be the case with the Git 2.23

The diff: munmap() file contents before running the external diff

While running the external diff from, the diff tool, it is safe to assume that we are trying to write the files which are in question.
Now on Windows OS, there must not be any other process locking an open handle to the files or the mapped region.

So please make sure that your git diff itself is not holding on any of the open handle to your files in question.
