Thin clients use an embedded operating system with a fixed amount of disk space. Dell recommends you to save files that you want to keep on a server rather than on a thin client.
drive Z is the on-board volatile memory (Dell Wyse RAM Disk) of the thin client. It is recommended that you do not use this drive to save data that you want to retain.
For information about using the Z drive with roaming profiles, see Participating in Domains .
Drive C is the on-board non-volatile flash memory. Dell recommends that you avoid writing to drive C. Writing to drive C reduces the free disk space. If the free disk space on drive C is reduced under 3 MB, the thin client will become unstable.
