The following table describes the configurable settings for this component.
|Enable FBWF||Check to enable.|
|Cache Type||Select Dynamic, Dynamic Compressed, or Pre-allocated. Dynamic is the default.|
|Maximum Cache Size in MB||Specify overlay cache size; defaults to 64 MB. FBWF overlay cache is limited to a maximum size of 1GB.|
|Disable page-file support||Check to disable the creation of a page file.|
|Disable System Restore||Check to disable system restore.|
|Disable Background Disk Defragmentation||Check to disable background disk defragmentation.
Note that if another component hs the two registry keys within it that this option is attempting to disable, then checking this option might have no effect if that component is built after FBWF. Components that are known to share registry keys with FBWF and could potentially disable this option include: Background Disk Defragmentation Disable, Enhanced Write Filter, and Disk Defragmenter. For more details please see Disabling Disk Defragmentation in Windows XP Embedded Help.
|Disable Low Disk Warning Notification||Check to disable low disk warning.|
|Number of protected volumes||Enter the number of volumes to protect. Each volume is configured in turn by clicking on the Prev and Next buttons.|
|Protected Volume #||Displays the current volume number.|
|Volume||Displays the drive letter of the current volume to be protected.|
|Write-Through Files and Folders||List those files and folders for Selective Write Through, separated by newlines. Note that the full paths should not contain the drive letter or environment variables. There is no mechanism to detect possible inconsistencies between the resolved value and the drive letter.|
