How do I change the owner of a shared folder?
If you're the owner of a shared folder, you can transfer ownership to another member by changing the folder's options on the Dropbox website. Once ownership is transferred, the new owner will be the only person who can unshare the folder or remove members. Please note that you must be the current owner of a shared folder to transfer ownership. By default, the original creator of a shared folder is the owner.

The owner is likely the person who originally invited you to the shared folder. If you don't see an owner for a shared folder, the owner may have already left it. If this happens you can contact the original owner and ask him or her to first rejoin the folder, and then transfer ownership to you.
If this solution isn't feasible, you can create a new shared folder, drag the contents out of the old folder and into the new folder, and then re-invite members of the old shared folder to the new shared folder.
If you're the owner of a shared folder and leave it without transferring ownership, the shared folder will be without an owner. In that case, you can always rejoin the shared folder and be reinstated as the owner. You can then choose to transfer ownership using the steps above.
