File class AS3 / AIR: let user choose only save location, not file name or extension

Question

When using browseForSave method, is it possible to let the user choose only the location of a file, and not the file name or the extension?

I'm creating an encrypted file, and I need its name and extensions not to be changed by the user.

Thx!

EDIT (AFTER SOLVED)

I was simply looking for the browseForDirectory method. Shame on me. :)

For a reference on how to open a browse dialog to choose a folder see the example here:

once you have your directory you can piece that together with code here to save a file using the FileStream object:

copied here since it's an external link

    private function saveFile():void{
        var myPattern:RegExp = / /g;
        var newFileName:String = fileName.text.replace('.txt','');
        if(newFileName.length > 1){
            var file:File = File.desktopDirectory.resolvePath("Files/" + newFileName.replace(myPattern,'_') + ".txt");
            var stream:FileStream = new FileStream()
            stream.open(file, FileMode.WRITE);
            var str:String = contents.text;
            str = str.replace(/\r/g, File.lineEnding);
            stream.writeUTFBytes(str);
            stream.close();
            fdg.directory = File.desktopDirectory.resolvePath("Files/");
            fileName.text = "";
            contents.text = "";
          } else {
              mx.controls.Alert.show("File name is required", "Error Saving File");
          }
    }
