D7: easy way to upload files from a menu link

Not sure if i am being stupid, but I’m unable to find an easy to have an “upload file” link on the navigation menu which then prompts the user to upload a file or files either with a browse functionality or drag n drop.  Everything I have tested means the user has to “add content” and then they can attach a file to that content.  I’m keen for the files to be stored in the private file system.

Any help would be much appreciated.
