Yeah I thought of that Scook, but I have plenty on hand that are 4gig . .and one 32gig one that holds my W8 Surface OS backup - I removed the partition for extra space. So I am a little loathe to use it, lest it corrupts the OS data.
You may be right, might be just easier to go to the store and buy another 16 gig drive - although out here they are not $10
LOL, by the time I go to the store at 9am (it is 6.40am at the moment) and get home and copy X3 and then install, it would probably STILL be installing over wifi!
