然后就是配置jdk跟项目路径创建新项目

IDEA文件目录介绍

help目录帮助文档手册；

bin目录是一些执行和配置相关包

jre64目录是jre运行支持；

lib目录是运行用到的jar包；

licenese目录是许可协议；

plugins目录是插件

redist目录是一些杂项；

另有重要目录类似

C:\Users\Administrator\.IntelliJIdea2018.2

config是你对idea的配置的文件 这个文件保存好，假如其他电脑安装idea，启动的时候可以选择导入你的这个config

这样省得再重复配置了；

system目录是一些系统缓存文件，日志文件，临时文件，索引文件，包括本地历史文件等等，假如idea遇到运行奇葩问题，

请把system文件删除，大多数情况能解决问题；

IDEA优化配置，提高启动和运行速度

找到idea安装盘

D:\Program Files\JetBrains\IntelliJ IDEA 2018.2.5\bin

把这里配置改一下 启动就相当于来说快一点
