•Amount of RAM to be used for FBWF Cache — Shows (in MB) the amount of RAM (in MB) that is to be used as File
Based Write Filter cache for the next session. This value should be in the range of 16 MB to 1024 MB. There is an
additional check that this value should not exceed 1/3 of Total Available RAM.
• Advanced Cache Settings area includes options to allow you to improve the effectiveness of cache memory (Cache
Compression, Cache Preallocation, or None).
c. FBWF Warning Settings area includes:
•Warning #1 (%) — Shows the FBWF cache percentage value at which a Low Memory warning message is displayed
to the user; Default value = 85, Minimum value = 50, Maximum value = 90.
•Warning #2 (%) — Shows the FBWF cache percentage value at which a Critical Memory warning message is
displayed to the user, along with another message display counting down the number of seconds before automatic
rebooting occur; Default value = 90, Minimum value = 55, Maximum value = 95.
•Reboot Time Delay (in seconds) — Shows the number of seconds that will lapse before system reboot in the Warning
#2 (%) case of cache overflow.
d. Enable FBWF — Allows you to enable the File Based Write Filter and prompts you to restart the thin client. If you do not
restart the thin client, the changes made will not be saved until the thin client is restarted. After the system restarts to
enable the File Based Write Filter, the File Based Write Filter status icon in the desktop system tray turns green.
e. Disable FBWF — Allows you to disable the File Based Write Filter and prompt you to restart the thin client. If you do not
restart the thin client, the changes made will not be saved until the thin client is restarted. After disabling the File Based
Write Filter, the File Based Write Filter status icon in the desktop system tray turns red and the File Based Write Filter
remains disabled after the system restarts.
f. Defaults — Allows you to reset the FBWF Cache Settings area, Advanced Cache Settings area, and the FBWF Warning
Settings area to their default values.
g. File Commit area includes:
•File Path — Allows you to add, remove and commit files to the underlying media, delete a file path from the list if the
file is not to be committed. The system will not restart the thin client. The changes are committed immediately.
h. Current Session Exclusion List area includes:
File/Directory Path — Allows you to add and remove a file or directory to or from the exclusion list for the next session
retrieves the list of files or directories that are write through in the current session; the title of the pane is shown as Current
Session Exclusion List or the Next Session retrieves the list of files or directories that are write through for the next session;
the title of the pane is shown as Next Session Exclusion List. The system will not restart the thin client and the changes are
not committed until an administrator restarts the thin client manually.
Understanding the NetXClean Utility
NetXClean keeps extraneous information from being stored in flash memory. NetXClean clean-up is triggered by either a service
startup or a user log-off. It runs in the background and performs the clean-up invisibly and no user input is necessary.
NetXClean prevents garbage files from building up and filling the free space in the flash for example, if a flush of some files in the
File Based Write Filter cache puts junk in flash directories that must be kept clean. The NetXClean utility is particularly important
when multiple users have log-on rights to a thin client, as memory space can be quickly used by locally stored profiles and temporary
caching of information.
NetXClean TweakUI functions includes clearing:
• Run history at log-on
• Document history at log-on
• Find Files history at log-on
• Find Computer history at log-on
• Internet Explorer history at log-on
• Selected Items Now
• Last User at log-on
