I have just downloaded files for sewing patterns BUT they cannot be opened because they are not JPegs. They have extension names like ART CST DST EXP HUS JEF PES SHV VIP and XXX. What can I do? Do I need to buy expensive software for each of these file types. I found something that said it would open them and charge only 29 American dollars but when I went to pay it wanted over 50 Euros which is MUCH MUCH more!
I have put this under configuration etc but don't know if that is a correct definition not being fluent in computer speak.
