I have the Viking Diamond Deluxe and before that I used the Ruby Deluxe. I can download from the internet, etc, my machine reads them all. I always keep an USB in my purse just in case I find any designs I like. Friends of mine gave lots of Disney designs from way back in the day. I had just went to Walmart, grabbed a stick and she copied them onto it and never had to format, I also have a Brother emb machine, I'm going to pull up the manual and see if it wants the USB to be formatted. Its crazy when companies make things more complicated than they need to be.
