Wilson has a free resizer program. You can only still do as much as your hoop will allow. You have to follow the directions for resizing. I tried the crabbing the corner and enlarging (like you do in Windows) and it distorted the embroidery so that alot of it didn't stitch out. I was doing it in my software but didn't realize that you have to follow certain guidelines. Also, depending on the design you aren't supposed to enlarge anything more that 20%; some can't go that much larger.
I don't have your machine but I use a usb (smart thumb) to save the files to when I want to take them to the machine. You could also use the cable and connect the machine to your printer. If you didn't get documentation with you machine I'd contact the company about getting it. You can quilt as you go or hoop small sections; which can be very time consuming.
