I was just copying some freeware URLs for a friend and thought I'd share a few here:
This is a great source for all sorts of freeware and open source statistics application software. Almost everyone here can probably find something useful. Some are simple, others not, but it's all free, and there's tons of it!
Just a simple page for unit-of-measure conversions--very handy.
An excellent file undelete utility. The website defaults to German, but you can select your own language from the dropdown menu near the top of the page. This utility has saved me a few times, once in recovering some image files from a "bad" SmartMedia card.
A nice little disk cleanup program--gets rid of a lot of the trash on your hard drive in seconds, and can be run from a floppy or jump drive
