Using the FileStore E01S
As with earlier Acorn File Servers, you can't have two discs with the same name, so the command FSNAMEDISC comes in handy to re-name a disc. This is an advance on the Level 2 and Level 3 file servers, which don't provide the facility to change the names of discs. With those file servers, it can only be done by direct sector editing of the disc.
