   2. Download and install libraries module first and then only install views

      file downloader.

   3. Download PCLZip library using composer composer require pclzip/pclzip.

   4. Make sure that machine name of the field containing file is "field_file".

   5. Now create views and nodes with files field.

   6. You can download all the files attached to a view by adding

      "download-view" to URL.

 * Install the vfd module as you would normally install a

   contributed Drupal module. Visit

   https://www.drupal.org/node/1897420 for further information.

CONFIGURATION

-------------

 * How to Work with Node Downloads :

   1. Create field_file (machine name) in your content type.

   2. Once now just add string "download-node" just before "/node/xx" eg

      http://example.com/node/68  just make it

      http://example.com/download-node/node/68 and return

   3. The file in the corresponding node will be compressed and downloaded.

 * How to Work with View Downloads :

   1. Create field_file (machine name) in your content type and add this

      field in your view.

   2. The path for the view must be same as the view Machine Name eg if the

      Machine name for your view "myview" is "my_cool_view" then the path

      must be same as the machine name  i.e /my_cool_view.

   3. Once done now just add string "download-view" just before "/my_cool_view"

      eg  http://example.com/my_cool_view  just make it

      http://example.com/download-view/my_cool_view and return

   4. The file in the corresponding view will be compressed and downloded.

   1. Make sure you have already configured the required file/media field

      in one of your content type and already created a view as well.

   2. Configure the required settings in '/admin/structure/views/settings/vfd'.

      Here you have to provide view name and machine name of the file/media

      field as well as type of the field.    

   2. To generate the download link of files appearing in a view, take a note

      of machine name of the view.

   3. Once done now just add string "download-view" just before the machine

      name eg  http://example.com/download-view/{view_machine_name}.

   4. The files in the corresponding view will be compressed and downloaded.
