Clicking this tools option Datagraph will add the current storage location of your data file to Window's list of trusted locations. This way a number of annoying security warning messages are avoided.
If the current data file location is already added as trusted location you may receive the following indication.
Note: If you have MS Access, trusted locations can also be managed under Options-Trust Center-Trusted Locations. You may add new locations or remove previously created 'trusted locations'.
