注：此方法适用于JetBrains的系列产品，包括IntelliJ IDEA，WebStrom，PyCharm等。
（1）打开安装路径下的属性文件
D:\Developtool\IntelliJ_IDEA_2016\bin\idea.properties
（2）修改属性配置
用notepad++等文本编辑器修改idea.properties文件，找到配置信息中有${user.home}的字段，如idea.config.path，idea.system.path：
1 # Use ${idea.home.path} macro to specify location relative to IDE installation home.
2 # Use ${xxx} where xxx is any Java property (including defined in previous lines of this file) to refer to its value.
3 # Note for Windows users: please make sure you're using forward slashes (e.g. c:/idea/system).
4
5 #---------------------------------------------------------------------
6 # Uncomment this option if you want to customize path to IDE config folder. Make sure you're using forward slashes.
7 #---------------------------------------------------------------------
8 # idea.config.path=${user.home}/.IntelliJIdea/config
9 idea.config.path=E:/Personal/.IntelliJIdea/config
10
11 #---------------------------------------------------------------------
12 # Uncomment this option if you want to customize path to IDE system folder. Make sure you're using forward slashes.
13 #---------------------------------------------------------------------
14 # idea.system.path=${user.home}/.IntelliJIdea/system
15 idea.system.path=E:/Personal/.IntelliJIdea/system

17 #---------------------------------------------------------------------
18 # Uncomment this option if you want to customize path to user installed plugins folder. Make sure you're using forward slashes.

30 # Maximum file size (kilobytes) IDE should provide code assistance for.

（３）重启IDE，如果指定目录下生成.IntelliJIdea文件夹，则说明修改成功。
