Where are workshop files located?

[QuickLoad]

I'm done with some workshop files so I unsubscribed from them, but it did not free up space on my computer. So I went to arma's annoyingly hidden files of 107410, went through all of them individually to find out which were the ones that I had unsubscribed from. For some reason, a 7GB mod only was about 100MB in it's folder, so i'm having trouble finding the mods. is there some way where they aren't listed 130958103958112059712, it's quite tedious..

note that you have to enable something like "see hidden files" to acsess it
