.. _sec-api-fileops-retrievelocation:

Retrieve files from specific location
=====================================

.. http:get:: /api/files/(string:location)

   Retrieve information regarding the files currently available on the selected `location` and -- if targeting
   the ``local`` location -- regarding the disk space still available locally in the system.

   Returns a :ref:`Retrieve response <sec-api-fileops-datamodel-retrieveresponse>`.

   **Example**:

.. _sec-api-fileops-uploadfile:

Upload file
===========

.. http:post:: /api/files/(string:location)

   Upload a file to the selected `location`.

   Other than most of the other requests on OctoPrint's API which are expected as JSON, this request is expected as
   ``Content-Type: multipart/form-data`` due to the included file upload.

   Returns a :http:statuscode:`201` response with a ``Location`` header set to the management URL of the uploaded
   file and an :ref:`Upload Response <sec-api-fileops-datamodel-uploadresponse>` as the body upon successful completion.

   :form file:      The file to upload, including a valid ``filename``.

                    to SD card was requested and the printer is either not operational or currently busy with a print job.
   :statuscode 415: If the file is neither a ``gcode`` nor an ``stl`` file (or it is an ``stl`` file but slicing support
                    is disabled)

.. _sec-api-fileops-retrievefileinfo:

Retrieve a specific file's information
======================================

.. http:get:: /api/files/(string:location)/(path:filename)

     * ``print``: Optional, if set to ``true`` the file will start printing directly after selection. If the printer
       is not operational when this parameter is present and set to ``true``, the request will fail with a response
       of ``409 Conflict``.

   Upon success, a status code of :http:statuscode:`204` and an empty body is returned.

Delete file
===========

.. http:delete:: /api/files/(string:target)/(path:filename)
