I am sure that at least one time, you have run into a situation where you wanted to delete a file, but Windows wouldn’t allow you to do it because the file was already in use by another program or because the access to the file you wanted to delete was denied for some reasons. In this case you should know these messages:

The source or destination file may be in use
Cannot delete file: Access is denied
The file is in use by another program or user
There has been a sharing violation
Make sure the disk is not full or write-protected
