Microsoft Windows- Folder/File Name Issues

Hey did you know you can't create a folder named "con" (without "" that is simply con) in windows. Hehheee really interesting na. Not only con but you also cannot create folders or files like Aux, lpt , com etc This is something pretty cool...and unbelievable... Try it out yourself... Else I will tell you later. Because now my friend is saying how this is happening. So i can tell you later. *************************** Hi geeks, thanks for your comments. The above problem is because con is a name reserved within the OS. It is just like a Keyword in a programming language. In the case of Linux, you can have any name but the precedence of path will take place. When i firstly heard about this i thought, wow, grate. But after knowing the reason behind this now i feel heee. So the above problem is not cool and unbelievable. Thanks to ViswaPrabha for helping me. But if u write =rand(100,50) in MS-word(2000 or xp) and press 'enter' key. See what happens?
