[QUOTE="cwa107, post: 1036169, member: 24098"] Well, first off, let's get our terms straight here: Memory (also known as "RAM") is a space that programs are loaded into in order for the CPU to process them. Memory is purged every time you reboot your computer. It is also freed when you quit applications. Hard disk space is semi-permanent storage. It's where your operating system, applications, documents and data are stored for the long term and it remains occupied even after you turn your computer off. Generally speaking, you want to have 20% of your hard disk clear. So, if you've got so much data stored on your Mac's hard disk that there's less than 20% free space available, it's time to either clean up (delete) data or move it elsewhere or upgrade the hard disk. You can see stats on your hard disk by right-clicking Macintosh HD on your desktop and clicking "Get Info". That will yield a window like this: [IMG]http://home.comcast.net/~cwa107/forumimages/2010-04-14_2229.png[/IMG] Here you can see that nearly 300GB of my 430GB is still available. As far as memory goes, you can speed things up just by not keeping so many programs opened simultaneously. In your example, you indicate that quite a bit of your memory is being used at the moment in time you took that snapshot. If the snapshot is representative of how many programs you need to have opened simultaneously to ensure you're productive, then you might want to consider a memory upgrade in order to give yourself a bit more latitude when you're working.
