Hi Christopher,
In RAMP, your local drives should automatically be mapped. They may not have the same letter designations you have locally, but they should all be there. The easiest way to test this is to "Save as" a document in Tessitura and check the drives available to you. You can also see the drives available by double clicking "My Computer" on your RAMP desktop, if you have access to it.
Hope this help!
