What i want is that a user can select a complete path in his local drive and then a file (which is in the war folder of my app right now) will be saved in that selected user location

I am using File upload in GWT to upload my files , its working fine , will i use FileUpload for Download as well?

Also for a second option if there's a possibility to get the location which user have selected for example d:\downloadfolder, my problem will solve, i will do the rest !

below is the code for uploading , Please help me with Download 

final String UPLOAD_ACTION_URL = GWT.getModuleBaseURL() + "upload";
initWidget(panelImages);
final FormPanel form = new FormPanel();
form.setAction(UPLOAD_ACTION_URL);

form.setEncoding(FormPanel.ENCODING_MULTIPART);
form.setMethod(FormPanel.METHOD_POST);

VerticalPanel panel = new VerticalPanel();
form.setWidget(panel);

FileUpload upload = new FileUpload();
upload.setName("uploadFormElement");
panel.add(upload);

// Add a 'submit' button.
panel.add(new Button("Submit", new ClickHandler() {
    public void onClick(ClickEvent event) {
        form.submit();
    }
}));

form.addSubmitCompleteHandler(new FormPanel.SubmitCompleteHandler() {
    public void onSubmitComplete(SubmitCompleteEvent event) {
        if(event.getResults().contains("DataBase Restored")){
            Window.alert("Database Restored !");
        }
    }
});

panelImages.add(form);

You can't do this from GWT because JavaScript has no access to the local hard drive. The best you can do is initiate a download normally (e.g. show a link to a file that the user can click). Depending on their browser settings they'll either choose a location for the file or it will be downloaded to some default location. You cannot know that location with just JavaScript.

If this is a project requirement I think you'll need to include a heavier-weight plugin like java or flash.
