I have a Brother 4000d and I use "Buzz explore" as a software program on my computer to store all my embriodery designs. That program allows you to see the design as a picture, unzips files, orginizes them in what ever catagories I want. I use just a 1GB or 2GB memory stick to use just the files I want to use for a project copy them from my computer to the stick and then put the stick in the sewing machine and it will see them. Be careful downloading some of the great big designs (larger than 5x7) your machine wont read them unless you have a machine that takes larger hoops or you have other computer software that can split the designs to fit the size hoops your machine reads.
