I'm not 100% sure but I think that is all you can send to the machine is one at a time.
As for Receiving you can send All, but ir sends all the programs into one big program with Prog # and M30 separations.
Have you tried the FNC on your machine or is it an older control?
FNC will help so you don't have to transfer programs but read a selected program from the USB. One catch is that Background Edit is not functional while in FNC Mode.
