Administrators need to know the following information
about local drives and saving files.
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
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 written to the File Based
Write Filter cache or directly to the flash if the File Based Write
Filter is disabled during normal operations include:
-
Favorites
-
Created connections
-
Delete/edit connections

the flash memory clean, see

NetXClean Utility
