file_size is a virtual field provided by the oik-fields plugin.
You can use it whenever a shortcode supports the display of fields, using the fields= parameter
and when the post_type being displayed is an attachment that has a file size.
Here we use it to display the file size of attachments to this shortcode example.
[bw_table post_type=attachment fields=title,file_size,excerpt]
