Recently, I had the special fun of migrating a new client’s site over to a new host. Everything was going smoothly and quickly until I got to the Files folder. It contained a 4-gigabyte hodgepodge of images, thumbnails, pdfs, known site backups and unknown site backups (Yes, unknown! I don't count the WordPress version of the site from six years ago as a "known about" backup). It got me thinking about one part of Drupal that I think many take for granted: The Files system. Drupal is three-part system: Database, Code and Files. When planning a site architecture, often the Files folder gets treated like the red-headed step child of the three; forgotten, neglected and rather ignored. However, that’s not the way it should be. Drupal is a content management system.
