Saving Files and Using Local Drives
Administrators need to know the following information about local drives and saving files.
Thin clients use an embedded operating system with a fixed amount of flash memory. It is recommended
that you save files you want to keep on a server rather than on a thin client.
CAUTION: Be careful of application settings that write to the C drive, which resides in flash
memory in particular, those applications which by default write cache files to the C drive on the
local system. If you must write to a local drive, change the application settings to use the Z drive.
The default configuration settings mentioned in Managing Users and Groups with User Accounts
minimize writing to the C drive for factory-installed applications.
Drive Z is the on-board volatile memory (Dell Wyse RAMDisk) of the thin client. It is recommended that
you do not use this drive to save data that you want to retain.
For RAMDisk configuration information, see Dell Wyse RAMDisk.
For information about using the Z drive with roaming profiles, see Participating in Domains.
Drive C and Flash
Drive C is the on-board non-volatile flash memory. It is recommended that you avoid writing to drive C.
Writing to drive C reduces the free disk space. If the free disk space on C drive is reduced under 500 MB,
the thin client will become unstable.
NOTE: We highly recommend that 500 MB of disk space is left unused. If the free disk space is
reduced to 300 MB, the thin client image will be irreparably damaged and it will be necessary for
you to contact an authorized service center to repair the thin client.
The File Based Write Filter (if enabled) protects the flash from damage and presents an error message if
the cache is overwritten. However, if this message occurs you will be unable to flush files of the File
Based Write Filter cache and any thin client configuration changes still in cache will be lost. Items that are
