NEVER JUST TURN YOUR SYSTEM OFF
Always shut your system down from the Desktop.
By shutting down from the Desktop you will ensure that:
1. Any new or altered files that were being compressed in the background
will continue to be compressed and saved before the system is stopped.
2. ZipStream is shutdown correctly which in turn will ensure that any
changed configuration information is preserved.
3. ZipStream is idle at shutdown, ensuring the most reliable operation of
your system.
