Quickest way to find out line count in txt file?

Does anyone know how to find out the quickest way of returning the amount of lines there are in a text file?

Tried using fileread and looping until EOF is found using a count but takes 2 long.

Any ideas?

I don't know of any better way of counting the lines besides going over the entire file looking for line breaks... Maybe if you implment it with pure C (extension DLL) it will be faster.
