New embroidery software won't open old floppy designs

Help any ideas. I purchased Wilcom Embroidery Studio and now my floppy designs disks that are DOS format will not open. I have added Trusizer 9 but that does not have DOS format either. Any ideas please share with me. Thank you

can you say exactly what you cant open?
DOS disks can be opened by any software in the world
Non - disks can not be opend by all the softwares.
You may be a little wrong giving your explanations.
Hope a lot of people here can help you with this case.
So maybe you have to give little more details. For example: DOS disks can be 720 KB or 1.4 MB,
second: you ment you use "open" menu of these "New" softwares, or you use "embroidery disk","Open.."

Hope you understand my meaning
