using SeleQ, what are the C, D, E, Z drives?

i hope this isn't a dumb question, im just a new user of 3650.

i have installed Seleq.

from the way i understand it. Drive C is the phone memory
and Drive E: is the MMC..

but what is Driver D and drive Z?
they seem to contain the same folders?

thanks..

the d and z drives if not mistaken must be the rom that's why they cannot be formatted.

Drive D is for wap use and drive z is the fixed drive that cant be deleted, and the main symbiam OS is installed on that drive.

Which drive is the memory card?

Drive E: is memory card, and drive C: internal phone memory (4 Mb)
