When you save a Design Page it will ask you to choose which Stitch File type you want to use. For example a Baby Lock / Brother embroidery machine owner will choose .PES as the stitch file type. In addition, the program will also silently save a working file (.BE) thus saving you the extra step of saving it separately. As mentioned earlier, the working file allows you to edit your designs including text. If you want to save individual files (not both stitch and working) you have all the options on the File menu.
