I have a Dropbox Basic plan - and to date, I've only been on that plan. I deleted files more than 30 days ago (but less than 180 days ago), which means they aren't available for me to recover. With the Dropbox Professional plan (and similar plans), I'm able to recover files that were deleted up to 180 days ago. Does that mean that if I now upgraded to one of those plans, I would be able to recover those files I deleted between 30 and 180 days ago? Or would I have had to already been on one of those plans before I deleted the files, in order to be able to now recover them?
