Allow no document or sound files - how?

[Blueiris]

I don't want my users to be able to upload documents or sound files. From what I see in the docs, you can put "ALL" in the config, or list the file types, but is there a setting that will disallow all docs or sound files?

[Joachim Müller]

yes: an empty field will disallow all files of that type.

Thank you! Solved.
