The design files must be .pes or .pen to be used in Brother, Babylock, Simplicity, Bernina, White (and maybe another machine brand.) You can unzip and move or copy to your desktop and they will be viewable on the 'basic' page. I don't like to clutter my desktop, so I've kept folders of designs in "My Documents'. You can choose hoop size on the opening page--if the design is too large for the hoop size you've chosen, you will not be able to write it to the card. The process is to move the designs to the right side of the page until the bar shows 100%--that's all you can 'write' to the card. Next time you proceed the same and a message tells you the card will be erased. That's okay--you still have the designs in your computer. Have you read the owners manual? Sounds like foreign language, but go slow--one step at a time. You will love it.
