Free Automated File Management Tools

"Need to keep your hard drive from being crapped up? Are you a power-downloader with no organizational skills? Do you want to see exactly where the space on your hard drive is going and have your computer automatically shuffle and sort new files around? You're in luck. We've assembled a batch of freeware utilities that are, without a doubt, the most essential file management tools you'll want to have on your PC. We use them to automate mundane tasks like file moving and deletion, and better still, to determine exactly where all the wasted space on our drives are going. We would kill to have these feature integrated into Windows Explorer, but no dice thus far. But we can't complain much, because we've saved so much time with these small utilities that we can't ever think about going back to a life without them."

This article covers Auto Delete, SysExporter, SpaceMonger, WinDirStat, WinDirStat, and Download Mover.  Any other essential tools we should know about?  Post in the comments.
