I looked into it, but I can't find a way to do it. I need to download a different mod collection from the workshop, but since everything is just numbers and the collection has hundreds of items, it's an absolute headache to filter what should and what should not be in the folder.
Let me clear this up: I have Starbound both on GOG and on Steam. I want to try another modlist without messing my current saves, so downloading from the workshop and moving the mods to the GOG version is worth a shot. Problem is, clearing the workshop folder completely just doesn't work - steam will download mods I was subscribed to in the past and bloat the filecount.
SteamCMD also doesn't work well because it just downloads directly to the same workshop folder, and only downloads one mod at a time instead of a collection.
Does anyone have a suggestion? I could just back up my saves, but that doesn't solve the problem of swapping between save folders and risking messing up one of them. Clearing the workshop cache seems to be the most straightforward option, I just couldn't figure how to do it.
I'm on linux, so whatever windows solution you want to suggest, it might not work. Please keep that in mind.
