I have a folder with a bunch of subfolders that I want to compress invidiually using 7zip. I really have no clue how to go about it.

It should go something like so:
What is the nth's folder's name? Nth folder's name is "x". Compress "x" as "x".7z. n++. Loop.

(basically atm I can't be arsed to figure out how to do it myself yayayayay)
