Look at it this way, the file is a bunch of 1 and 0 in order. When you delete it basically scrambles the 1 and 0's into a random order. Doing this once, like Windows does, can make the data recoverable, fairly easily.
Using a third party tool will delete or scramble the data numerous times. The US Dept of Defense does 3 passes on data and I believe the NSA uses 7 passes.
I like using Secure Delete from Sysinternals.
Here is a list of other free tools to help you delete your file more securely.
