8280, WinXP SP2, Java 6 (u10 beta)
Just noticed ".IntelliJIdea80/system/caches/attrib.dat.data" file is 345 megs big (after cleaning up ".IntelliJIdea80/system" and opening the project again)
Does it need to be that way ? The whole ".IntelliJIdea80/system" folder is now taking ~ 500 megabytes.
Since IDEA keeps an ".IntelliJIdea80" folder in the home directory - this happen to be a C:/ drive on Windows and my C:/ drive had only 750 megs free.
Now only ~200 are left :(
