This does not matter. I've done the prior updates numerous times with other files in the drive. As long as it is on the ROOT of the drive and named swdl.iso, the radio will pick it up.
You beat me to the punch on providing a direct download. But you only have RA4 up and I have RA3. I'll still do my direct downloads for RA3 and RA4 with instructions later (can't do it at work).
