I have an old dos system with many thousands of designs on it. I upgraded awhile back to version 11.40. I would like to transfer my embroidery designs to the new system while maintaining the capability to alter them. However when I download the kwk, pch, and ica files my Sierra wont recognize them. My computer says they are on the disk. How do I rebuild them on Stitch Era? Please help. If I just download a dst version I cant alter it as it saves it as a DST file not a DSG. Thanks for your help.
