Write filters protect data from unwanted modifications by redirecting write operations to another location or overlay. Use the Enhanced Write Filter (EWF) VIs to protect volumes and redirect writes to a disk location on another volume or to the RAM. Use the File-Based Write Filter (FBWF) VIs to protect files and folders in a volume and redirect writes to the memory cache. The Write Filters VIs are available for VIs under a Touch Panel target. Refer to the MSDN Web site at msdn.microsoft.com to learn more about write filters.
LabVIEW supports the Write Filters VIs, which you use to enable, disable, and configure write filters, for touch panel devices. You must target a touch panel device to use the Write Filters VIs.
