Thanks for posting here, @rmtbylani.
It sounds like you’ve uploaded your files to Dropbox, which has caused your Dropbox account to go over-quota.
Even in this case though, you can still access all of your files here. Are you having any issues when trying to access this page?
Also, do you want to remove the Dropbox app from your mobile device, your laptop or both?
Let me know, and we’ll go from there.
