    I want to create a text file via after effects on a mac. I am using the code below but I don’t know what is going wrong as I am unable to create the folder. I have enabled Write and network access inside after effects. Please help.

    var scriptFolderPath = File($.fileName).path; //alert(scriptFolderPath)
    var s = File(scriptFolderPath + "/testfile.txt");

    Hey Avinash, check the code below, stripped it down from my scripts, but should be fine / close to it.

    var logFileName = "build-log"; //Log file name
    var scriptFolder = new File($.fileName).path; //Script path folder
    var logFile = initiateLogFile(scriptFolder, logFileName);"a"); //Open file for appending
    logFile.write("_____"); //Add your logging message
    logFile.close(); //Always don't forget to close after writing the file

    function initiateLogFile(rootLocation, rootTitle) {
    var logFile = File(rootLocation.toString() + "/" + rootTitle + ".txt");
    logFile.encoding = "UTF-8";
    if (!logFile.exists) {"w");
    return logFile;
