I can't find a way to change the directory idea stores its cache-s in anywhere in the settings. Is it possible to change it after installation? I would like to change it in idea 3, idea 4 and idea 4.5, and I am using the Windows version.

If you used the installer, than the setting is in the "lax" file. if you
used directly the *.zip version, then you can edit idea.bat or idea.sh
from your "idea_home"/bin directory. If I remember, the cache and other
resources are stored in the "IDEA_SYSTEM_PATH" , so you have to change
it. Default, this setting is "~/.IntelliJIdea/system" i.e. your home
directory. A good practice is to change this to: "%IDEA_HOME%/system",
so that more versions of IDEA can coexist on the same computer.

Ahemed.
