I am using the following code in order to retrieve sub folder names from the path declared. This works fine but how do I then remove the path name so that the array is a list of just folder names?
var myPath = Folder ("Z:/My File System/Me/Work Files/Design");
var folders = getFolders (myPath); 
function getFolders(sourceFolder) {
var folderArray = new Array();
var sFolders = sourceFolder.getFiles ();
var len = sFolders.length;
    for (var i = 0; i < len; i++) {
    var sFolder = sFolders[i];
        if (sFolder instanceof Folder) {
            folderArray.push(sFolder);
        }
    }
return folderArray;
}
Instead of returning:
Z:/My File System/Me/Work Files/Design/One
Z:/My File System/Me/Work Files/Design/Two
Z:/My File System/Me/Work Files/Design/Three
Z:/My File System/Me/Work Files/Design/Four
I need:
One
Two
Three
Four
