Mimetype mappingΒΆ
Nextcloud 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 Nextcloud to show the audio icon.
By default Nextcloud 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 Nextcloud. Instead the file mimetypemapping.json should be created and
modified, this file has precedence over the shipped file.
