title: How to decompile to java files intellij idea
body: <p>IDEA has a great built-in feature - decompiler. It works great.I can copy source code, but I cannot find option to extract all decompiled java classes to java files.<br>
  This project has a lot of java classes and packages, so I will be to long to copy this manually.<br>
  Does anyone know how to extract to java source files.
    Thx</p>
