If you want to restore your company file you copy the QuickBooks company file onto your hard drive (default is to place it in your Documents folder). Inside of that will be the backup of your QuickBooks company file and the backup of your Attachments folder.

The disk image also allows for the storage of all your attachments on the backup.

We deliberately made the 'CD' read-only because with previous systems users were opening their backups, entering transactions, and then later opening their real company files and saying the work was deleted by QuickBooks.
