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