How To Use Regular Expression To Validate File Path(Folder Location) In JavaScript and JQuery?

Suppose you want to validate a folder location like: d:\bang pics\tom-check-6.0\inner  or D:\bang pics\tom-check-6.0\inner we can do it using  Regular Expression.Here is the expression :

/^([A-Za-z]:)(\\[A-Za-z_\-\s0-9\.]+)+$/;

Explanation:
1.  ([A-Za-z]:)     for d: or D: (drive name)
2.  (\\[A-Za-z_\-\s0-9\.]+)+     for \folder_name (recursive way)   + sign for recursion (e.g \my\music\etc).
