    +## Sample: Download and Upload Files <a name="sample"></a>
    +Use the File-Transfer plugin to upload and download files. In these examples, we demonstrate
several tasks like:
    +* Downloading a binary file to the application cache
    +* Uploading a file created in your application's root
    +* Downloading the uploaded file
    +## Download a Binary File to the application cache
    +Use the File plugin with the File-Transfer plugin to provide a target for the files that
you download (the target must be a FileEntry object). Before you download the file, create
a DirectoryEntry object by using `resolveLocalFileSystemURL` and calling `fs.root` in the
success callback. Use the `getFile` method of DirectoryEntry to create the target file.
    +window.requestFileSystem(window.TEMPORARY, 5 * 1024 * 1024, function (fs) {
    +    console.log('file system open: ' +;
    +    // Make sure you add the domain name to the Content-Security-Policy <meta>
    +    var url = '';
    +    fs.root.getFile('downloaded-image.png', { create: true, exclusive: false }, function
(fileEntry) {
    +        download(fileEntry, url, true);
    +    }, onErrorCreateFile);
    +}, onErrorLoadFs);
    +>*Note* For persistent storage, pass LocalFileSystem.PERSISTENT to requestFileSystem.
    +When you have the FileEntry object, download the file using the `download` method of
the FileTransfer object. The 3rd argument to the function is the success handler, which you
can use to call the app's `readBinaryFile` function. In this code example, the `entry` variable
is a new FileEntry object that receives the result of the download operation.
    +function download(fileEntry, uri) {
    +    var fileTransfer = new FileTransfer();
    +    var fileURL = fileEntry.toURL();
    +        uri,
    +        fileURL,
    +        function (entry) {
    +            console.log("download complete: " + entry.toURL());
    +            readBinaryFile(entry);
    +        },
    +        function (error) {
    +            console.log("download error source " + error.source);
