You need to take it into a disk manager in your software and write it as a shv format. This process makes the floppy readable by the D1. In 4D you should open the software, click on accessories, disk manager...load the designs you want into the available spaces and click on write disk.
Yes you would have to use the Disk manager program to write the designs to the floppy in the SHV format which is the format that the Designer 1 uses.
You can bring in any format design other than the ART format into the Disk manager program and when you click to write to the floppy disk the program automatically puts the design on the floppy in the SHV format.
Disk manager program should be located under Accessories in 4D.
BettyBoop13, if I remember right - you have to take it into the Quicklink and down to the Accessories and over to the 4D Disk Manager USB and then you have to get the file from the location on your PC (get as many as you think you might need - you have all sorts of space that you can put on the floppy) and it formats it for the Designer I on the floppy disk when you click on the UP Floppy ICON - try it and see it that helps.
