## Description

WordPress’s built-in file-management is built primarily for handling “media”. But
sometimes there’s a need for curating collections of files within WordPress, not
necessarily as media which will be displayed, but simply as files.

This plugin adds an abstraction called “file groups” to WordPress. Each file group
can contain multiple files, which are presented elegantly to the user. All files
in a file group can be downloaded together as a zip archive as well.

In addition, file groups can be tagged and these tags are used to associate particular
file groups to your posts. Two widgets, “related file groups” and “upload related
file group”, are supplied to make it easier to integrate the display of related 
file groups with your posts.

The plugin currently uses the PHP [ZipArchive extension](http://php.net/manual/en/class.ziparchive.php)
to support the batch download functionality.

This plugin is a component of the [MIT Educational Collaboration Space](http://ecs.mit.edu)
project.

### Migration

File Groups has some tools which make it easy for you to migrate files which are
not in file groups (known as “orphans”) into file groups.

First things first, you will need to (temporarily) unhide the native Media Library
from your admin by adding the following to your `wp-config.php` file:

    ```
        define( 'FILE_GROUPS_HIDE_NATIVE_MEDIA', false );
    ```

In the Media Library, you will now see a drop down which will let you “show only
orphans”. Select any collection of files there which you would like to migrate into
a file group, and then select the “create new file group” action from the “Bulk 
actions” menu and click “apply”. A new file group will be created for the files 
you selected.

Alternatively, individual orphan files have an action called “create singleton group”
available to them if you hover over its row in the table.

## Screenshots

 * File groups have tags and these are used to “relate” file groups to posts. A “
   related file groups” widget and “upload related file group here” widget are included.
 * [[
 * Files in your WordPress installation not attached to file groups (“orphans”) 
   can be easily turned into their own file groups. See the “Migration” section 
   of the readme for details.

## Installation

 1. Upload the `file-groups` folder to the `/wp-content/plugins/` directory
 2. Activate the plugin through the ‘Plugins’ menu in WordPress
 3. Optionally activate the “related file groups” and/or “upload related file group”
    widgets.

You should now see a new item in your WordPress admin menu called “File Groups”.
By default, File Groups will hide the native Media Library. You can keep the native
Media Library around by adding the following to your `wp-config.php` file:

    ```
        define( 'FILE_GROUPS_HIDE_NATIVE_MEDIA', false );
    ```

If your WordPress installation has some files uploaded from before File Groups is
installed, you will most likely want to migrate these files into their own file 
groups. See the “Migration” section under “Other Notes” for more information.
