默认IntelliJ IDEA产生在C盘文件 的位置

IDEA 修改配置文件的位置：

你安装软件bin的同级目录下：

eg:

````

# Use ${idea.home.path} macro to specify location relative to IDE installation home.

# Use ${xxx} where xxx is any Java property (including defined in previous lines of this file) to refer to its value.

# Note for Windows users: please make sure you're using forward slashes (e.g. c:/idea/system)

.#--------------------------------------------------------------------

-# Uncomment this option if you want to customize path to IDE config folder. Make sure you're using forward slashes.

#---------------------------------------------------------------------

idea.config.path=${user.home}/.IdeaIC/config

#---------------------------------------------------------------------

# Uncomment this option if you want to customize path to IDE system folder. Make sure you're using forward slashes.

#---------------------------------------------------------------------idea.system.path=${user.home}/.IdeaIC/system
