.minecraft

 .minecraft (or simply  minecraft on macOS) is the game directory of Minecraft: Java Edition and the launcher directory of the Minecraft Launcher.

The game directory stores data managed by the game client, such as game configuration, worlds and resource packs. The launcher directory stores data managed by the launcher, such as its own configuration, the game client program, game libraries and assets. Those two directories, while technically distinct, are normally unified (in the default layout) into  .minecraft.

Below is a table showing the default path of  .minecraft.
