Can you try
- stop your site (not iis).
- try to delete temporary files
the second option can be (dangerous) 1. kill the asp.net workflow (this is a criminal blocking of files in the temp folder) 2. Try to delete temporary files.
it is difficult to understand which process actually blocks files, if it runs in an ISAPI environment, that is, in an exp wp file, you can use some file monitoring tools to find out the identifier of the process that accesses / blocks the file, then use the task manager to kill it .
greetings.
