My Husqvarna converts all programs automatically except ART. The new Diamond converts it too. There are many free conversion programs at many of the free design sites. At the moment I can't tell you which sites (it's very late and I'm not thinking too well). If you don't find one, I'll hunt one up tomorrow or Sunday, if you let me know.
I have Viking and I can use pes. So I imagine it would work the other way around. If you have software bring it into that and change it.
You can always convert them using a conversion sotwfare or most digitizing program.
