Systems Folder?, How to free up memory... Options

[alreed]

hi forum,

I'm wondering if anyone can help?

I have an iBook with a small, but sufficient hard drive of 28GB (I use external hard drives when I'm recording in Cubase or working with big files).

The problem is, even though my applications and iTunes(under User) only take up 10GB, since everything else is on the external hard drives, my hard drive says I'm using 27GB in total. That's 17GB unaccounted for! It was ok when it was 3-4GB, but 17 seems a bit much. Do I need to reinstall, or is it something wrong with my systems folder?

Any help would be REALLY appreciated, I've had this problem for the past year now!

Thanks...

I stand corrected, don't know what I was thinking there with the swap sizes, I guess it goes back to when I didn't have enough ram to hold the huge photoshop files that I was running. Photoshop uses ram in A different way to audio apps from what you say lepetitmartien glad to know that.. If you open a 10000x10000 pixel(100megapixel) file in photoshop which I have just done on my machine; a G5 with 4gb of ram you gat a file that is 286mb but has a scratch file of over 900mb, now Photoshop has always been a memory hog and has also always handled memory in a different way to OSX but its good to know that Logic or DAW's don't pull the same trick.

cheers
