What is the “_cff” sub-folder in the PC Access folder?



What is the “_cff” file folder




When PC Access 3.0 (actually first appeared in 2.16) or later is installed, a folder is created named _cff. This folder stores controller firmware files (files with cff file extensions) that are downloaded when you check for product updates. The cff files are used to flash the firmware in flash memory controllers (released after February 2008).
