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
