On my Macbook I once asked Dropbox to do backup of my Documents folder. What it did was to create a folder called "My files in Dropbox" and put all of my files under this folder. But under My files in Dropbox, it also created a folder named "Files on my computer". And under Files on my computer are "My files in Dropbox" AND another copy of all (or some, I am not sure, but many) of my files in Documents. This goes on ad infinitum it seems. These files take up all the storage of my laptop.
I've already contacted Dropbox Support three times via live chat (I have a paid subscription plan) but received no solution so far. Anyone else with the same problem? Did you find a solution?
