Download to D drive instead of C drive on an eee pc?

I have an eee pc that is driving me crazy.

Apart from the fact that the keyboard is absolute garbage and has a mind of it's own, the C drive is so TINY that by the time I have put on my antivirus/firewall etc it is full (The only programme that I run on it is Microsoft Money) I have no virtual memory left on this pesky piece of hardware......

The D drive is bigger but try as I may I am unable to get any of my antivirus programmes etc to download to it (I use Firefox)

How do I get everything onto the D drive instead of the C drive? Is there an option to download all programmes to another drive? Yeah, I know it's a very basic question...........

Thanks in advance

PS Unfortunately this eee pc :crap was a gift, so I feel obliged to use it

 

Thank you!!!!!

Ha! Ha! Windows now wants to automatically install some updates!! Agghhh...There
is no room!!!! I may put the rstore disk in and start from scratch again......Now where is that extrnal hard driv??.....or buy som acid and drop th flippin' thing into it!!!!!! See the letter E only works somtims!!!!!!

 

Can't seem to get the ext disk drive to work......
Everything is jam packed onto the C drive but the D drive is virtually empty.....
I have Windows XP as the OS

 

Sorted my drive to K fine! Thank rnal drive will notxteYou!
(See! Keyboard really playing up today!....I was trying to say Thank You very much)

My LG external disk drive still will not behave! The instructions for system recovery are:- Press <esc> on boot up then select the boot drive.......the <esc> button does not do anything but the F8 button gets me into something "sinister" regarding booting up,safe mode etc but doesn't give me the option to choose to boot from my newly named "K" drive.....

Hey ho.....

 

SORTED!!!!! Got the eee pc restored to original state!!!! Got the downloads to automatically download to D!! The Keyboard still :crap but I'll have to live with that!!!

THANK YOU!!!!!!!!!

Kind regardss

keyboard is the same is my laptops one-the problem s where your mouse cursor is, and if you ta off the touchpad it changes where the cursor actually is in the box, putting the end of your sentence in the middle-you just get used to it after a while.
