Uploading mp4 and other files

CentOS 7.4, Pydio 8.0.2

I installed Pydio so that some of my other teams could upload of content they create. However when they upload mp4 or Adobe pek files, mp3, it tells them forbidden. Do I need to specifically allow those in the pydio config?

no you should be able to upload any kind of files, your issue seems to be either related to the data upload configuration of PHP or just rights to upload X Size files for your users.
Did you try it yourself, or with an admin user to upload any of those types(mp3/4 & .pek).
