I've been studying Java for a few months and I want to start using Intellij IDEA.  

 For each book or source of information I have created a subdirectory and then another subdirectory for each chapter. So my current structure is something like this: 

```
/java/headfirst/chapter1
/java/headfirst/chapter2
..
/java/tutorialspoint/
/java/youtube/newboston/
/java/deitelHTP/chapter1/
/java/deitelHTP/chapter2/
..

```

That works very well when using vim and the command line. 

Now with Intellij I'm looking for feedback on how best to organize my files. It seems like I need to create a project(or import) for my existing directories and that seems to be OK. Should I be doing this some other way or is there a better way to organize my files? 

So far just about everything I've worked on has only a few class files and I haven't really learned about packages yet.
