So I just installed a new Dropbox account today, and it synched itself to my laptop and cleared everything off it. All my business and client files, everything that's ever been on my computer is now deleted, and stored only on Dropbox. And it won't let me move anything back because it says i'm already over the account size limit and it won't let me remove anything unless I pay for the upgrade.
I'm just trying Dropbox for the first time too. This default install feature is very annoying. Your files are probably still on your computer, but are now in the Dropbox folder.
In my case (on Windows 10) I only moved the Documents folder. The solution was to find the documents folder in Explorer, right-click, then properties, then choose the Location tab. Click on Restore Default. If you've also moved the Desktop, I'm guessing a similar process will work for that.
I managed to get my old files back, but now my brand new Dropbox account is already overfull because it copied my entire hard drive, and they won't let me delete any files unless I upgrade. How am I supposed to manage/delete items from my free account? I unlinked my account from my device, but no change.
