Adobe and/or windows are not able to open machine embroidery files. To see them you will need specialized software designed to do that. There are many different softwares you can purchase, I use Buzz Explore, and Embird has already been mentioned but there many others available as well. There are also free software packages you can download to try as well. I have not used any of these, but I did Google 'free software to view embroidery files' and a number of options did come up. If you read the blurbs about them you may find one that meets your needs. Sorry I am not able to recommend one but they do appear to provide the basic functions you are looking for and the screen shots look similar to what I have in Buzz Tools. Good luck!
