I initiated a sync change on one our computers, un-syncing about 50% of various top level folders (and their contents) to that device. Then I noticed on our OTHER computers/devices those folders and MANY others were now missing!? Maybe Dropbox accidently "un-synced them everywhere" ... which it shouldn't have! I next logged into our Dropbox directly via browser and sure enough our entire directory structure was riddled with missing/incomplete/relocated folders
I have opened a support case for this, #26124591. But to date, only partial restorations have been made. I have since requested that our ENTIRE directory structure be correctly restored prior to March 5th, as that's the only way to resolve this huge mess Dropbox made of our files and ensure we get ALL our data back.
Does not instill confidence in Dropbox ... a caution to those of you un-syncing files/folders. Hope you have a recent backup of your own making at hand. If Dropbox can't restore your account folders/files accurately (or at all) your data be gone :-(
