Simply spoken: directory on an Amiga disk is always exactly in the
middle of the disk (or partition).

More detailed: In that middle you find the "Root block", which is
the main directory. But you must note that the organisation of
the directory and its entries differs heavily (better: totally)
from that on old C64 which you obviously refer to. Such detail
informations are found in any good book about AmigaDOS internals.
The official book for this is the "AmigaDOS manual" (sp?) from
Bantam Books.
