Another tip, at least what i use in my installation: I always point every profile to a subfolder in .minecraft. In case i've created a "profiles" folder inside .minecraft, and inside it i create a folder for every profile   For example:   .minecraft |_versions |_profiles     |_1.12.2_forge     |_default (the default profile the new Mojang launcher adds)     |_snapshot (the default profile the new Mojang launcher adds if you enable snapshots support)
