I have a basic (free) account with 5gb limit. Somehow, my main folder (unshared) was allowed to go beyond that to 7gb, and is now locked up with the message above. I have the obvious recourse of purchasing more space, and presumably, this will "unlock" my data.
It's very strange that storage capacity be allowed to go beyond the quoted limit, then I be unable to access the folder in order to either retrieve/clean up the data? This is clearly hijacking and forcing me to buy a plan from dropbox. I'm not even allowed to look into the directory and delete wha'ts not needed? It's just being held randsom. I'm not going to pay dropbox a cent for this kind of aggressive treatment. Either let me in to my folder to access what you made available in the first place per your end user aggreement, and allow me to remove data and meet quotas, or decide you don't ever want to have me as a paying customer.
