You will have to unzip the file in your Computer Documents and then open them from documents to Hatch..I have hatch its a big learning curve but definitely great software..
My wife has had a Janome 11000 SE from new and it's still good as new..doing 50-60 towels a year for birthdays-new borns general sewing etc
I sold my 11000 which I had for 12 years and purchased a 550E mainly for the large hoop as I don't have to split large designs and will stitch 120k stitches in a single session
