When you subscribe to an item in the Workshop, does it take up storage space on your computer?

[Tigre feroz 2012]

I've downloaded a lot of mods but when I click on the Teardown folder on my computer, and click on the mods folder, it's empty.

But I'm guessing subscribing to Workshop items does take up storage space, as my free storage has gone down as I've downloaded a lot of mods.

Normally you subscribe, steam downloads them and then integrates it into the Steam Modfolder/ Workshop folder with the games ID.
Teardown then detects them and when starting the game you can click on play and aside from career and sandbox etc... you can also click on "mods" where you can activate and make local copies of the mods.

For me, mods don't show ingame tho, So I manually have to copy them from the steam workshop download folder to teardowns modfolder.
