Handy Software to Determine Hard Drive Usage - HD Graph

Every now and again I find a program which is very handy.  We all know that flight simulator is hard drive hungry; once scenery files and other specialist files are added the hard drive can fill up very quickly.

HD Graph is a standalone program (does not need to be installed to your computer) that allows you to interrogate your hard drive to graphically display the hard disk space usage.  It shows all the directories and subdirectories of the hard drive on a single graph, allowing to see the largest directories at a glance. 

At the moment the tool is available free of charge from the HD Graph website.
