I created a shared link for anyone with the link, and had tinyurl give it a nice short name without a tinyurl account so can't delete that. If I now unshare the folder in Dropbox that should kill the tinyurl from working, correct? Then can I rename the folder, share with a link again and get a different url to use? I know files have their own I'd and renaming will not affect the link you first got for sharing
Deleted link as suggested. Created a new folder and copied contents to it, then got new link for it, and used that for new tinyurl link. Also created account with tinyurl so can manage it and other me ones easier. Thank you.
