I thought I was just receiving a file and somehow got added to a Group and my files were all added to a folder with my name within the group. I need to get out of the group without losing my folders and documents.
How can I do this? (also submitted Question in Twitter)
As it sounds like you accidentally joined a Dropbox for Business Teams account with your own -previously individual- account, your best bet here would be to reach out to the team's admin and have them convert your account back to an individual one.
You'll see a list of the admins on your Dropbox Business team at the top of the page.
From there, you should reach out to them (via email or text for example) and ask them to convert your account back to an individual one. You can forward them the relevant Help Center article as well to expedite matters further.
