I have a customer who owns a Mac and when she attempted to download an unzipped embroidery file (jef extension) she was greeted with the message this was not possible, that it had to have a .dmf extension and she was given the option to use both (nameoffile.jef.dmf) This did not work at all. How do you download an embroidery file while keeping the extension intact? She transfers her file to a jump drive and then to her machine. We tried downloading directly to the jump drive - same message. She is going to try to use her Windows parallel and see if that will work. I would appreciate any assistance/advice!
