problem reading and writing files in subdirectories from javascript

    Jun 09 2014 | 8:14 am
    I would like to read and write text files from javascript. I would like the text files to be located in a subdirectory, but even if I specify a proper file path, the text file writes in the same directory as the javascript file.
    Do I miss something?
    my test function:
    function test()
    var f = new File('/testdir/testfile.txt','write','TEXT');
    // the file 'testfile.txt' appears in the same directory as the js file, not in the testdir subdirectory.
