E01 and E20 FileStore Dealer Test Disc


Here we can work through a map chain, and I've entered the sector number of the root directory. It is in fact the JesMap for any disc object which is recorded as its start sector, with the actual contents of the object being referred to in the JesMap sector; so - the root directory actually begins at the sectors after its JesMap, and is three consecutive sectors long. The last sector is not a full sector, and the JesMap stores the low-byte of the file length only.
