It’s actually very simple. For example, let’s say my hobby is “Vintage Cars”, and I want to “bookmark” or “favorite” a story about the 1958 Cadillac Eldorado. Because I keep a folder of “Classic Cars made in the 1950’s” and a folder titled “Cadillacs”, I want to bookmark my web story about the 1958 Cadillac in 2 places. The 2 places are the following 2 folders, “Classic Cars made in the 1950’s” and “Cadillacs”. When I attempt to do this, the webpage “only” stays bookmarked in the last place I saved it. In this case, that would be the 2nd folder titled, “Cadillacs”. I want it save in “both” places. Your solution is really no solution at all because not only would your idea take an inordinate amount of time, it would be painstakingly slow to do that for every entry I want to bookmark in more than one folder; Furthermore, it would also be impractical and inefficient.
