Yesterday I took some time off to clean my office systems – a Dual Xeon desktop and a T41p laptop. The effort would have cost me at least 2 days, if not for the following tools!

CCleaner CCleaner – The best utility for cleaning up the temporary files, IE/Mozilla/Opera cache and lots of other junk. This used to be called Crap Cleaner, If I remember right :-)

WindirStat Main Window		 WindirStat – This tool allows you to visualize the file groups in your disk. There are umpteen number of tools out there that can do this, but I like the simplicity and effectiveness of this. Also, it runs off the shelf (no installation, I love it). Another thing I love about this small utility is its progress bars, it shows a pacman like character going from one end to the other, which is kinda cute! Check the images, click to enlarge.

Windirstat - Progress bar
Duplicate File Finder Duplicate File Finder – However organized you may be, you will be amazed to see what this tool digs out. It can apply CRC32 or MD5 on the files in your hard disk to find out the same content in multiple files. It takes its own sweet time to run, but very effective and highly recommended. An analysis on C:\ (120GB) is still running, almost 45mins now.

Let me know if you use some other tool not listed here.
