Dear,
I'd like to suggest that audio and media files were supported in preview item and batch coding.
As many investigations use smartphone data, tis fairly commons to and item (chat) bring WhatsApp audio and video file (.ogg and .mp4).
Today we need to download the files and play using VLC or media player. The problem is that not all reviewers has Download permission, restricting the people that can review CHATS.
Thanks
Delson Gonçalves
