Create a txt file in Extendscript

Hey!

im trying to create a script that creates a txt file but i can't do that...

that is the function code:

var scriptFolderPath = File($.fileName).path; // the URI of the folder that contains the script file  
var TimerFolderPath = scriptFolderPath + encodeURI("/ProjectTimers_sources"); // the URI of the folder for your script resources  

StartButton.onClick = function(){ 


var JFile = new File(TimerFolderPath + encodeURI("/File.txt"));
var content="That is a text file";
File.write(content);


alert("File created!");
}

and it doesn't creates any file...
