DO, as a rule, KEEP YOUR PROGRAM FILES on the SAME disk as YOUR OPERATING SYSTEM FILES !

(excuse the CAPS, but this is worth shouting about, huh ?)

Put your 'data' files (i.e. music and video and text and DownLoads) on another disk, if you like...

Hard Disk Drives are really cheap now... Install a 160GB or so and shift all of your 'personal' saved and shared stuff to that new disk...
FREE as much space as possible on the main C:\ drive where your OS and Program Files are located...
You need to have NEVER LESS than 20% free space remaining on your 'Main Hard Disk Drive' in order to be able to adequately perform the basic functions of the Windows OS and... AND, especially, to be able to perform a correct de-fragmentation of your 'main drive'...

Some may return and argue these points I have made here...

TS... They are talking nonsense...

Remember--- De-Fragment OFTEN...
Never fill your HDD beyond 80%
Use an application such as WindowWasher to help you to REALLY remove all that garbage that Windows collects !!!

Wipe Wipe Wipe !
