I dont know of any equivalent for Windows.

In my brain, I figure out that adding tags makes you less worryful about where you place files, because files can be found simply via a search as long as you remember the correct tag – even files kept in different folders would match as long as the tag search query matches.

I think ‘setting up rules’ to move files automatically into designated folders makes more of work. Computers are supposed to ease our work, not create additional work. In this case, additional work is required to set up rules for moving files, and you need to *think what rules you want to set up. It is that thinking (time & energy) we are trying to skip.
