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

Configuration directory

Syntax

%APPDATA%\JetBrains\<product><version>

Example

C:\Users\JohnS\AppData\Roaming\JetBrains\IntelliJIdea2022.1

您可以使用IDEA .config.path属性更改IntelliJ IDEA配置目录的位置。

System directory

Syntax
%LOCALAPPDATA%\JetBrains\<product><version>

Example
C:\Users\JohnS\AppData\Local\JetBrains\IntelliJIdea2022.1

您可以使用IDEA .system.path属性更改IntelliJ IDEA系统目录的位置。

一般这个目录文件比较大，所以修改这个文件则可以

修改后：

这样就可以把原来默认目录下的文件删除掉，减少C盘的空间
