[FEATURE] Proton Prefix

[massatt212]

the ability to delete proton prefixes on desktop mode, without hunting down the folder location

[Vysp3r]

I don't know where those are, do you have an example with more data for me?

[massatt212]

Steam compatdata folder

home/deck/. local/share/Steam/steamapps/compatdata

[Vysp3r]

That would delete every proton prefixes tho no? You would lose a lot of data if not backed up properly. I would need to add a way to list the games you have installed to delete a specific prefix and I don't plan on doing the game list part of ProtonPlus right now.

[Vysp3r]

Or maybe I don't understand completely the prefixes, if so just try to explain it to me in a simple way so that I can understand what you really want.

[massatt212]

Alright np, but deleting data is not a problem just got to use a warning message before you do, and take your time with it.

[massatt212]

The proton or wine prefix install the game files like directx vcrun and so on for proton it get corrupted when changing proton versions sometimes, so they tend to say delete it and install fresh, cause steam deck has one built in to delete it, but desktop users have to find the id and delete it manually, a program to speed that up would be very nice.

[Vysp3r]

So just to make sure, you want to be able to delete everything in the /compatdata folder? I am pretty when they say delete it and install fresh they mean for the proton prefix of a specific game no? Otherwise if you have a game without steam cloud you would lose save data no?

[massatt212]

Yes delete specific game, and game cloudless games, that will be there responsibility,that's why u can give them a detail warning ⚠️

[Vysp3r]

I will add that feature for the next update.

I just thought about, but if you want to be able to delete the proton prefixes for specific games that will not be possible for now. Not until I implement a way to list Steam games and so on. Which is why I will put this on standby for now.

Take a look at proton tricks, they can tell which exact steam game it is.

[Vysp3r]

Most of them are you using python which makes it easy for them. I have to do most thing by myself hence why my application is way smaller in size then ProtonUp-Qt. I planned on adding the 'Games' tab for v0.5.

[massatt212]

Ok

We have discussed it while triaging old issues, and decided that it's out of scope.

• If you uninstall a game in Steam, it automatically deletes the compatdata for that game.
• If you are still using a game, you need its compatdata. People don't go around deleting it themselves.
• And if you really want to delete a compatdata yourself, use https://steamdb.info/ to find the ID of the folder to delete. Search for the game and you will see the ID in the address bar of the browser.
