Hi Warner,
I do not find this a small issue. Did this occur with every CC subscriber who changed the default location of their Creative Cloud Files folder? If so, why does there seem to be no communication by Adobe about this? Could you at the least possibly post or pin information about this on the CC forum? If this had occurred on my old computer, less than 1 month ago, there would not have been enough space on my C: drive. What would have happened then?
