清理IntelliJ IDEA中C盘中的缓存文件

idea在c盘中产生的缓存文件大概800多m，占据了c盘的很大空间，可以把这个东西移到其他盘符下，我的操作是移动到E盘

# path to IDEA config folder. Make sure you're using forward slashes  
idea.config.path=${user.home}/IntelliJIdea/config  
  
# path to IDEA system folder. Make sure you're using forward slashes  
idea.system.path=${user.home}/IntelliJIdea/system  
  
# path to user installed plugins folder. Make sure you're using forward slashes  
idea.plugins.path=${user.home}/IntelliJIdea/config/plugins 

原本的配置文件在idea的安装目录下的bin目录下的idea.properties直接打开进行修改成

 idea.config.path=E:/IntelliJIdea/config

 idea.system.path=E:/IntelliJIdea/system

 idea.plugins.path=${idea.config.path}/plugins

 idea.log.path=${idea.system.path}/log

这样重新启动肯定是配重新配置，比较麻烦，直接把在c盘下的文件夹直接拷贝到E盘重新启动idea即可
