Where does ripple emulator create files?

I create a file with ripple emulator successfully at this path:

fullPath: "/myAppFolder/myFile.txt"

This is the code:

filesystem.root.getDirectory("myAppFolder", {create: true, exclusive: false}, function(dir){

    dir.getFile("myFile.txt", {create: true, exclusive: true}, function(file){console.log(file);}
            ,function(error){console.log("error create file: "+error.code+":"+error.message);}
            );
    }
    , function(error){console.log("error create dir: "+error.code+":"+error.message);}
    );

Also where can I see this file? Is it on the hard drive?
