Whats the fastest way to delete the most amount of disk space?

I just bought the burning crusade addition of world of warcraft,but I need more disk space for it to finish installing.(more than 1.8 gb is required, but only 37.6 mb is available.)
I spent about an hour last night deleteing music and pictures,and it still didnt give me enough space.
Does anyone know the fastest way to get rid of the most amount of space?

if you have any random applications already installed into your computer, you can delete those if you don't use them.

for example..
I have a mac, but some applications I have recently deleted were called "stickies," "calculator," "ichat," and "safari" and it saved me a lot of memory.

OK. If you use Windows you could download my little utility Dirlot http://soft.km.ua/soft/dirlot/index.en.html. It shows interactive folder size report.

So if you need to free up some space on hard disk then start the utility and go to the root folder of some partition (C:\, D:\...). Thus you will get diagram showing relative size of its subfolders. Select the folder that takes the most space and dig deeper until you define individual files that have big size and take the most space. If you do not need them anymore then delete them. Repeat the procedure if needed.

Doing this way you will be deleting just the files that are really big without paying much attention to lesser ones which even being deleted do not free much space on disk.

And I beg pardon for my English but hope you have cought what I mean.

try defraging and delete any unused apps or format your hard drive and it will be all clean but DO NOT do that if you dont know what your doing of by another hard drive and hook it up

GET A NEW HARDDRIVE BUT GET AN 80 OR THE CHEAPEST ONE IF you NEED THAT SPACE WHAT HAPPENS WHEN you NEED TO UPDATE WARCRAFT
