If you placed your new USB into the 200E it will have placed 2 folders on the stick. The outside one will be EMB and inside that there will be another. That 2nd folder is where you .jef files must be placed. Also if the designs are to big for the hoop on your machine, they won't open either. You have just one hoop and it isn't large but it will sew many nice designs - I think about 4" square is the limit.
