File transfer

Hi, I’m trying to implement the ‘File transfer’ plugin. It is returning full download but I can’t see the file in any folder. This is the json response:

download complete: {
    "filesystem":"<FileSystem: files>",

This is my code.

  download() {
    const url = 'urlserver/testfile.pdf';
    const fileTransfer: FileTransferObject = this.transfer.create();, this.file.dataDirectory + 'testfile.pdf').then((entry) => {
      console.log('download complete: ' + JSON.stringify(entry));
    }, (error) => {
      // handle error

i am also facing the same issue please let me know if you have found any solution.
