File-Based Write Filter (FBWF)

File-Based Write Filter (FBWF) works at the file level instead of the sector level on
protected disks. By default, FBWF protects the entire disk. However, selective write
through exceptions can be granted to specific files and folders. Writes to folders with
write-through exceptions will persist when the device is restarted.
Advantech provides a utility to run FBWF. Follow the steps outlined below to enable
this function.
1. Access Start Menu->All Programs->Advantech->AdvWF and the click on FBWF
Utility.
