Yes and no. That is the simple solution, but it is not robust. If a network share is not available when Ignition starts up, that mapped drive letter will not be available later. It doesn't fix itself.
The proper answer is to not use mapped drives. AT ALL. Use UNC paths directly to the network resource wherever you would have used a mapped drive. For this to work properly, you need to change the user account under which Ignition runs to an account that has the necessary privileges on your network. The default account (LOCALSYSTEM) has no network privileges.
Using this approach also avoids putting user/password combinations into your configuration file.
(BTW, you linked to the old v8.0 documentation. It should be this link.)
