Find Large Files and Folders

There is a fast and handy download available at Treesize that allows you to see at a glance how your hard drive space is allocated. If you sort the results by size, you can see which files and folders are unnecessarily eating up your storage space.

I recently used this tool after installing Windows 7 and discovering I only had 3 gigabytes of space left. This tool allowed me to find a folder called windows.old that was taking up an extraordinary 40 gigabytes of space. I deleted it, and presto, 40 more gigabytes of space were freed up.

Thanks to Angie Asmus for suggesting the tool to me.
