Time-To-Live for Uploaded Files
-------------------------------

For users with system administrator privileges 
to the ``data/Settings`` model, the time-to-live for uploaded files 
can be managed. 

.. note::

   Files that are uploaded from file management menus on
   the user interface and listed as instances of ``data/File``
   are not affected.

Uploaded Bulk Load files and imported JSON files are affected,
however:

* For Bulk Load files, the file is kept for as long as there is
  an instance of ``data/BulkLoad`` attached to it. So a schedule that is
  more than 24 hours in the future is not impacted, because when we schedule
  a bulk load for the future, we create a ``data/BulkLoad`` instance.
  The instance is cleared when the Bulk Load is executed.
* Monthly License Reports that are uploaded to the database by the internal schedule
  are not removed. For more details, refer to the License Feature Guide.
