regx: '/^(?:[\w]\:|\/)(\/[A-z_\-\s0-9\.]+)+/g'

With version: '^(?:[\w]\:|\/)(\/[A-z_\-\s0-9\.]+)+\.(txt|gif|pdf|doc|docx|xls|xlsx)$'

Expalnation :^(?:[\w]:|/) -- Begin with x:/ or //

[A-z_-\s0-9.] -- valid characters are a-z| 0-9|-|.|_ (you can add more)

(txt|gif|pdf|doc|docx|xls|xlsx) -- Valid extension (you can add more)

I think this will works:

 var pattern = "[(c|C|D|d|E|e)]:.*";
 var str = "E:/dir1/dir2/dir3";
 var result = str.match(pattern);
