What is filling up my hard drive?

[mkornik]

Is there a program/utility that I can use to tell which directories are filling up the hard drive on my laptop? I have a 70GB partition on my hard drive that is seems to be 90% full, but I have no idea what is taking up all that space. If I scroll down the list of directories in explorer (including hidden ones), none of them show as being the culprit, and if I total up all the reported sizes, it accounts for less than 30GB. How can I find out what is filling up my hard drive?

any suggestions are appreciated. oh, I'm running Vista.

This utility has been recommended several times on the lounge...

How much disk space is used for System Restore?

Do you use Hibernate? If so hibernate creates a file called hiberfil.sys which often exceeds 3 GB. If you do not use or do not need hibernate, disable hibernate and delete the hiberfil.sys file.

I would also check on temp files. These can increase in size drastically over a relatively short time. I use CCleaner to help corral temp files, and clean leftover junk in my registry.

Thanks for the help. I have used CCleaner, but I will try the other suggestions.
