Today I was quite shocked when I looked at my hard drive’s free space to find that over 70% was full, and I couldn’t work out why the hell it was so full.

So I thought I’d better check out where my biggest files were on the computer – but sadly Windows has no real way of sorting your whole hard drive into file size (at least not Vista, anyway) which is a bit of a bummer.

So I did a quick Google, and found a very useful free application which will search your computer for the 100 biggest files on your hard drive. It’s really easy to use and setup as there is no installation – you just download the 258kb file and run it. You can then navigate to the folders with the files you don’t want and delete them.

You just need to go to this site and download file with the ‘free download’ link. Then just run it and let it search your hard drive.

It helped me free up just over 12GB on my hard drive which was really handy since I need some space for the upcoming Windows 7 RC release.

Anyway, there you have it. A really handy application which I’ll place on the GEEK! Recommends page.
