LFI-00122:

Can only delete a file if we create it.
Cause: The delete file flag was specified for a file that was not created by this file operation. The ability to delete a file is not portable. As such the only deletion that is allowed by this package is if we know we want to delete the file when we create it.
Action: You can only delete a file that you create. If you need to delete a file that you do not create then you will have to find another means of doing so.
