get file name and path from dropzone

Hi,

I have a dropzone where I'm supposed to drop an image. The Image should be uploaded only if the user presses some other Submit button. I  have js:

var myDropzoneMeta = new Dropzone("#metaImage",
        {
            url: "/file/post",
            autoProcessQueue: false,
            autoDiscover: false,
            maxFiles: 1,
            addRemoveLinks: true,
            init: function () {
                this.on("maxfilesexceeded", function (file) {
                    this.removeAllFiles();
                    this.addFile(file);
                });
                this.on("thumbnail", function (file) {
                    //here is the problem  I need to get the file name and file path and put it in something
                });
            }
        });$("#metaImage").addClass('dropzone');

Then I have in my view 

<label for="metaImage" class="col-form-label">Meta Image</label><div id="metaImage"><div class="dz-message" data-dz-message><span>Drop Image Here</span></div></div>

and the script to handle the post

$.post("/umbraco/DealManager/Deal/SaveDeal",
        {
            'Id': @deal.Id,
            'MetaImage'://here I'm supposed to send the image file name and path

         })

Problem is how do I get the file name and file path from the dropzone?

Please help
