Do those workshop files get deleted from their computers after they disconnect/exit the game?

GMod manages the workshop files, and it doesn't delete any of them after players leave the servers.

so does this make it faster to join servers who have alot of addons?

Actually it'll take you the correct time to enter the server because you'll download what you have to. If it was fast before, things were missing, if it was slow, there were too many downloads.

What gamemodes does it support?

All gamemodes. DarkRP, Sandbox, Murder, TTT... It doesn't matter.

What is the difference between this and Addon Share?

UWD can run on dedicated servers, is fully automatic, includes some optimizations, checks for PointShop1 missing files, supports FastDL and ServerDL and has a different control panel.

Feel free to use whatever you prefer, Addon Share also works on its own way. But choose one or another, having both addons is redundant.

Only a few of my addons were installed (for others) but many of them still showed up as errors.

Usually it's caused by a bad configuration and sometimes GMod doesn't load the downloaded files correctly. To fix this, before joining a server first check if "workshop downloads" are enabled (Options -> Multiplayer) then, if it's still not working, just restart the game.

Where are the mods downloaded to?

how to remove addons that this addon downloaded [...]?

Many people ask "how to delete files"...

To send the addons we use two very common Lua functions:

• resource.AddSingleFile
  
• resource.AddWorkshop

So all downloading and storage is done by the game itself, not us. Our job is just to select the correct addons automatically, which is what every server owner needs to do manually without us. See, every server you've ever logged into is piling up garbage on your computer, that's how GMod works.

We can't clearly tell you how to clean up the game because there is no default or stable way to do that. The only official thing about this is the GarrysMod/FactoryReset-GMod.bat file, but running it will return your game to its original state.

Anyway, there are some Important locations in the current GMod version that store addon files and configurations. I really don't recommend to remove their content, but if you want to do so, there they are:

"steamapps\Workshop\content\4000" -- Newer GMod Workshop addons folder (since January 2020 update)

Iside "steamapps\common\GarrysMod\garrysmod":

• addons -- Legacy addons and older Workshop addons folder
  
• download, downloads and downloadlists -- ServerDL and FastDL files and folders
  
• cache -- Lua/Workshop generated cache
  
• cl.db, sv.db and mn.db -- SQLite databases (Make Steam check the game files if you delete these)
  
• data -- Addon generated data

I currently use the reuploaded version of P2P Hero, and I want to switch to UWD but I'm concerned that my friends will have to redownload all of my mods.

What has already been downloaded is not downloaded again, but AWD and P2P Hero send every mounted Workshop addon while UWD selects what's really needed (e.g. only the current map, addons for the loaded gamemode). If you use UDW with them, our optimizations will be lost, so choose just one of these addons.

Will this download the same Workshop items for every connection?

No, just once. Who manages the downloads is GMod and it doesn't delete the files.

Will the addon work if it is not downloaded on the server?

No.

My friend couldn't find addons like ragdoll or props on the spawnlist

UWD "Adds a Workshop addon for the client to download before entering the server." (https://wiki.facepunch.com/gmod/resource.AddWorkshop). That's it.

Unfortunately, this "missing spawnlists" behavior is normal and we don't like it either. The only solution I know is to locally create a spawnlists searching for each item in the Spawn Menu.

What happens to mods that don't include model/texture/sound/etc. files?

As long as the programmer has done his job correctly, GMod handles the scripts (.lua files) by itself (they are automatically downloaded by clients if necessary). So, in this case, our addon isn't needed and can be disabled without any problems.

Originally posted by "Such":

Is there a way to make the this addon only download specific addons?

No. What we select to download is what is needed (from Workshop), neither more nor less, so there's no need for manual configurations.

Also UWD is not designed to load addons on the fly, it just sets up the addons to download as soon as the server opens.

Is there anyway to get this to download custom addons that are not on the Workshop?

Yes. Check out our Legacy Addons Support topic.
