Thank you Jean for your answer.
The main problem is that I believe that it is a really needed feature that we have to have in the core of BBB, but from the start to now we have only very limited features related on deleting those unwanted files. I don't know why, but the developers can add the related code for deleting all kind of files related to recordings in the core of BBB in my opinion. If they want, they can comment them so they are not active by default, BUT if anyone needs to use them, they can un-comment them and edit them to match their needs.
I saw many people asking this and it is not even a clear updated solution that we can totally manage deleting all those kind of recording files without worried.
Deleting them manually or with scripts that we find in the forums with the risk of damaging the software functionality, is not really a good solution as far as I understand.
I really hope we see the team adding this in the future at the core of BBB.
Regarding to my problem, I deleted the script, and then rebuilt all the recordings, as there are more than 270 recordings, and hopefully, after 2-3 days all of them for 30 day back in the published and also appears in the Moodle.
I hope the team solves this for one time in a one complete solution for all types of recording files that I mentioned in my initial message and keeps it updated for all releases and versions.
After all, I want to thank the team for all their efforts for such good software.
Kind Regards
Hossein
