Regex to parse entire path?

Is there a regex which can parse a string which points to a file or folder (from the root e.g. C:)?

Language is Javascript.

Thanks

Well, actually there are several, but it depends on what exactly you want to parse. Do you want something like: "C:/.../.../nameOfFile.extension"? Or without the name of the file? Can you be more specific about the problem? Which is the input?

I made this code, really simple, which for a given path, gives you the path without the root.

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class TestProgram {

    static String path = "C:\\Folder1\\Folder2\\file.extension";

    private static void parsePath() {
      String newPath = "";
      String root = "C:";
      Matcher regexMatcher;
      regexMatcher = Pattern.compile("\\\\").matcher(path);
      newPath = regexMatcher.replaceAll("/");
      regexMatcher = Pattern.compile(root).matcher(newPath);
      newPath = regexMatcher.replaceAll("");    
      System.out.println(newPath);
    }

    public static void main(String[] args) {
       parsePath();    
    }
}

The output is:

/Folder1/Folder2/file.extension

I don't know if this is what you want, but you just have to play with methods. You will eventually reach the solution.

Why not skip the regex and just use split? 

var path = "C:\\Users\\Joe.Blow\\Documents\\Pictures\\NotPr0n\\testimage1.jpg"
var arrPath = path.split("\\");
var filename = arrPath[arrPath.length - 1];
var drive = arrPath[0];

etc.
