If I uninstall Minecraft Forge, will it also remove the mods I installed with the help of Forge or will it still be in my folder? And can I reinstall the Forge mod so I can play without any mods and have the new version of Minecraft? I have not yet got the game because I am gonna be doing a Minecraft roleplay but I sometimes want to play the game without any mods. I looked up how to disable mods but it doesn't answer the question I was asking.
Deleting the Forge client shouldn't remove any mods that you installed, the Forge client is just a way to access those mods, it doesn't actually contain the mods in the client. The mods you install are stored in a separate file then the client. If you want to play without mods then get the standard Minecraft client or Badlion client, either one should work.
