- Does it lock the file before it deletes it?
- Does it need to?
- If it does not perform file locking how can I make it safe between multiple processes?
Maybe this link will explain better. As far as I understand, deletion is an atomic operation so it does not need to lock the file. However, upon looking further, I found this link which shows the OS dependent nature of the delete operation. On Windows, it will necessarily need the file to be without a lock to delete it while on Linux you can delete a file while another process is using it.
