You can restore and overwrite your existing company, or you can restore to a new company.
If you select an existing company, you can Browse and select the company you want to restore to. If you select a new company, then the company will be named exactly as the backup file you selected on the previous panel.
Warning! If you select to restore to an existing company, you can browse to a directory and select a company to restore to. If you accidentally chose the wrong company, you could delete that company's data by overwriting it with the new company's data. So be very careful to make sure you've selected the right company to restore to. You should make a backup of your current company before restoring your data, in case anything goes wrong.
