HiFi Firmware update 5.3 (03/20/15)

I've downloaded the new files but have a question, since I'm using the HiFi module, do I keep the UCSETHIFI and Voicepak files on the flash drive? These were from 12.31.14 when the new HiFi modules came out. Or do I just need the three files on the USB stick? - privacy key file, bin and setup file? Please advise.
