I don't want my files to be deleted everywhere, just from a certain folder.
That's not what it means. It's referring to all linked devices. If you delete a file from a folder, that file will be removed from that folder on all devices (i.e. everywhere) that are linked to your account. It's not going to delete the file from any other folders elsewhere on your computer.
I have been a dropbox pro user for years and this is new-Like the other messages I often download a document to my desktop to temporarily use but save back to dropbox--I need to be able to delete the extra copy off my desktop without deleting it for dropbox. How can this update be changed--because it is new (only a few months) and changed how deleting works and it is a pain in the bottom. PLEASE HELP
