DOS command-line tool boot commands

The following table lists the EWF boot commands that are supported.

Boot Command

Description

 

 

All

Displays information about all protected volumes and performs a command, such as Disable, Enable,

 

and Commit, on each volume if specified.

 

 

Commit

Commits all current level data in the overlay to the protected volume and resets the current overlay

 

level to 1 upon shutdown.

 

 

Disable

Allows user to write to the image after the next reboot.

 

 

Enable

Prevents the user from writing to the image after the next reboot.

 

 

Commitanddisable

Combination of the Commit and Disable commands. This command will commit data in the overlay

 

upon shutdown. Additionally, EWF will be disabled after the system reboots.

 

 

NOTE: When using the Commit boot command, all the temporary contents will be permanently written to the flash memory or hard disk. In addition, all content accessed (and changes made) after running Commit, but before rebooting the system, will be written as well. This includes changes made during any number of login/logout sessions before the next reboot.

Using boot commands

To use the EWF manager boot commands, type the following syntax in a command prompt:

EWFMGR <drive-letter> —[boot command].

NOTE: Because the EWF manager commands are executed on the next boot, you must reboot the system for the command to take effect.

File-Based Write Filter Manager

WES includes the File-Based Write Filter (FBWF) console application command-line tool, fbwfmgr.exe. In addition to the DOS command-line tool, the WES image includes a write filter GUI.

Benefits of the File-Based Write Filter

The FBWF provides a secure environment for digital signage player computing. It does this by protecting the digital signage player from undesired writes. For the MP4 model, the write filter also extends the life of the digital signage player by preventing excessive flash write activity. It maintains the appearance of read and write access to write-sensitive or read-only storage to the operating system, making read and write access transparent to applications. File and/or folder exclusions can be configured to allow certain changes to persist, while preventing others from writing to disk.
