I am looking at buying a new cameo 4 after having had a Craft Robo which has been unused and sat in a box for about 4 years since we moved !
We had Design Master and Sil Studio on the old PC and i still have many GRA & GSD files.
I know I can use the GSD files but I cant remember what program used the GRA files or how I created them.

Can these be converted? Looking up on Google it seems to now be a MS Graph extension, but I presume it was to do with Graphtec/Craft Robo. So am i now unable to do anything with them in the Sil Studio?
I dont even know which edition of Studio i had so unsure if i will buy the latest edition or if I can find out from Silhouette which edition i had and upgrade.
Thanks for any help!
