   As an alternative press ALT + M on your keyboard.

Command Prompt

1. Open the Command Prompt (CMD) from the Start menu.
2. Go to the system directory by using DOS commands.
3. Enter the command, including the folder and filename of the backup:
   PKZIPC -comment <backup folder/backup name>.zip.
   The version will display onscreen.
