Hard Disk is full but not due to files

Question

What's using up my disk space?

Hello! I have a 40 GB hard drive which is full in explorer (10 MB remaining). The drive is NTFS running Windows 7.

In Explorer, I go to Tools > Folder Options I select 'show hidden files and folders' I unselect all options which start with 'Hide'

In Explorer, I select all. View properties. The 'size of files on disk' is 14 GB.

So how is my 40 GB drive full? Looking for investigation vectors and recommendations.

Thanks!

You may want to use something like TreeSize Free to figure out where your disk space is being consumed.

Another tool which does a similar function is WinDirStat, I like this one because it's a single executable with no dependencies.
