here is the code

Answer 1

now it works, target directory should be resolved.

here is the solution

window.resolveLocalFileSystemURL(cordova.file.externalApplicationStorageDirectory,
                      function onSuccess(dirEntry)
                      {
                          //alert(JSON.stringify(dirEntry));

                          fileEntry.copyTo(dirEntry, 'versions.txt',
                              function()
                              {
                                  alert('copying was successful')
                              },
                              function()
                              {
                                  alert('unsuccessful copying')
                              });
                      }, null);
