      Configure Files to display files inline instead of as attachments.

    - Disabling automatic email notification of file updates
      When an user downloads a file for the first time, Files sets a preference so that the user receives an email notification when the file is edited or commented on. The assumption is that users want to receive email about updates to the file. You can disable this notification using the files-config.xml file.
    - Disabling file versioning
      By default, when a user uploads a new version of a file it becomes the latest version, and all previous versions are kept. Users can see all versions of a file in the user interface. You can disable file versioning in the files-config.xml properties file.
    - Transferring ownership of user files
