To restore data from the backup copy, you need to create a Restore item. Press the "New item" button on the program toolbar to initiate the New Item Wizard. Choose a name for the new item and select "Restore item" as its type.

You can also create a new Restore item by double-clicking the index file in the Windows Explorer. Open the Windows Explorer, locate the index file (it should have the .obi extension) and double-click on it. Office Backup will start the New Item Wizard to create a new Restore item for the data specified in the index file.
