How can I delete a file that is in use by another process?

Question

When I try to delete a file occurs the following exception:

The process cannot access the file \'\' because it is being used by another process.<

Answer 1

If the file is being used you're out of luck in trying to delete it. I can't tell you based on your code what process might be using the file(s), but try looking here or here or here, or at any of the other questions that show up as related to this one for guidance regarding this issue, and by all means follow the guidance from @Cody Gray about using Process Explorer.
