Mimetype mapping ================ ownCloud allows administrators to specify the mapping of a file extension to a mimetype. For example files ending in ``mp3`` map to ``audio/mpeg``. Which then in turn allows ownCloud to show the audio icon. By default ownCloud comes with ``mimetypemapping.dist.json``. This is a simple json array. Administrators should not update this file as it will get replaced on upgrades of ownCloud. Instead the file ``mimetypemapping.json`` should be created and modified, this file has precedence over the shipped file.
