Title: Dollar sign?

Hi Roman, nice pattern. Out of interest though, isn't the escaped dollar sign superfluous? You have it as: \$? But, I'm not sure when that would get used? I presumed that you had it there to match an admin share on a mapped network drive such as: \\foo\C$\want.jpg but, as you can see the $ sign is actually in the next segment from where you have it in the pattern so, I'm not sure that it will ever get used? Cheers, - Darren http://regexblogs.com/DNeimke
