There are quite a few freebies to see your downloads. Wilcom is one of them. I have the Brother PE770 and that uses a USB stick also. Just make sure that you don't have too many downloads on the same stick. My machine can handle no more than 200 at a time on one stick. However, I save the PES downloads on one and than only transfer the ones I want to be working with on another stick. This way you don't have to search through all of them to find the correct one. The embroidery machine pictures are too small, not clear and only black and white , so I use the Wilcom (free) or ERA Universal to show my pictures in color on the computer, while I am embroidering.
