...very eloquently put sir! I'm sorry that you were unable to read - down through the comments and find that, I have identified that the previous pattern was indeed "Bullshit" - as you put it. I've also offered another pattern (in that very same comment) which probably does work when using the javascript regex engine.
Again, thankyou for your kind words of encouragement :P

The negative lookbehind assertion won't be supported in js so, most likely I can get around that by implementing it as a negative lookahead and move it the front the 2nd group; like so:
^([a-zA-Z]\:)(\\(?!=[ ])[^\\/:*?<>"|]*)*(\.[a-zA-Z]{2,6})$

Select Javascript and test the expression. Returns a syntax error.

Thanks OracleGuy! I've altered the pattern to allow for spaces (and other characters in accordance with the WinXP operating system). You can read about the changes that I made here:

Comment:
If there is a space in the directory name, the pattern returns a non match. Fixing that would make this pattern quite valuable.
