Motivation
The file type category "Multimedia" used to be used for multimedia files that could not be identified as neither audio nor video. This should be fixed now, so there should be none/nearly none files in this category.
Users will probably assume when filtering for "multimedia" this will search for audio and video (logical or) and will be confused if getting no results.
Acceptance Criteria
- The filetype "Multimedia" is not part of the list of file types anymore
