How to copy samples from the inbox to the ram?

hey elektronauts
i´ve just sent some sample via c6 to the model samples.
the files are now in a folder called inbox.
i need them in the ram, cause if i send new samples to the inbox
he´ll overwrite the samples, cause they are just numbers now, without name…

another thing, transfer ist not working on my mac, even if on osx high sierra 10.13.3
they say, my mac needs 64bit… i dont don t get this. where i can see, if my mac is 64 or 32bits?

thanks for help
and merry xmas
cheers martin
