Saving Files and Using Local Drives
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 Manager"
minimize writing to the C drive for factory-installed applications.
Note
For File Based Write Filter information, refer to "Using the File Based Write
Filter (FBWF)."
Drive Z
Drive Z is the on-board volatile memory (Ms-ramdrive) 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, refer to "Setting Ramdisk Size."
For information about using the Z drive with roaming profiles, refer to "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 size of the flash. If the flash size is
reduced to under 3 MB, the thin client will become unstable.
Caution
It is highly recommended that 3 MB of flash memory be left unused. If the
free flash memory size is reduced to 2 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. For information on the role of NetXClean in keeping the
flash memory clean, refer to "Understanding the NetXClean Utility."
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
