After installing IntelliJ IDEA, configuration files are created in the user folder of the Windows system disk by default. In my only 32G SSD, how can I make it like this, it's unpleasant. . Occupy now almost 1G. All right. Got her out today.
Find a properties file idea.properties in the installation path (for example: D:\IntelliJ IDEA\bin), open this file, the first three lines say:
# Use ${idea.home} macro to specify location relative to IDE installation home # Also use ${xxx} where xxx is any java property (including defined in previous lines of this file) to refer to its value # Note for Windows users: please make sure you're using forward slashes. I.e. c:/idea/system
You should know what it means by looking at the next four lines, for example: idea.config.path=${user.home}/.IntelliJIdea12/config
Just modify it to the path you want to set. After modification, the final lines are as follows:

这多了个#号啊。要把这个#号去掉打开这行配置才行
这下子可以把C盘占用的删除了！！！不过注意把以前配置好的转移备份
