File-Based Write Filter (FBWF)

File-Based Write Filter (FBWF) works at the file level instead of the sector level on

exceptions can be granted to specific files and folders. Writes to folders with write-
through exceptions will be persisted when the device restarts.
Advantech provide utility to operate FBWF. Refer below steps if you want to enable
1. Click Start Menu->All Programs->Advantech->AdvWF and click FBWF
