var string = 'file:///data/user/0/com.sleep.app/files/sleep-videos/video2.mp4';


var stringPart = string.substring(0,string.lastIndexOf("/")+1);

If only the filename changes try something like here

^(.+)/([^/]+)$

Try it at regexr. Your first group is the dirname, the second group the basename.

If you have further requirements/information (e.g. which tools you use), please refine your question.

I'm using `Javascript/Typescript`. – Sampath Jun 16 '17 at 06:47
i updated my answer (since before it resembled basename behavior, now you get both). does this work for you? – BNT Jun 16 '17 at 06:49

var url = "file:///data/user/0/com.sleep.app/files/sleep-videos/video2.mp4";

url= url.split("/");
url.pop();
url = url.join("/");
