I have been using copytrans manager for awhile now...

Can I distribute different 'genres' of music to different micro SDXC cards, as I want to change from my ipod classic to a Fiio X3?

The Fiio X3 only supports micro SDXC cards to 64GB, and my library is over 170GB. Fiio X3 claims to recognise 'itunes' libraries, so would I transfer my copytrans library back to an itunes library and go from there by buying 'tunespan'? Will tunespan work with a PC, rather than a Mac?

Or is there a free PC version that I could use with copytrans manager to save me the bother and expense?

Thanks for any advice...
