File Transfer Limit size?


i know there are already some discussions about the limit but they are very old and i couldn´t really find a solution.

I am using Openfire 4.0 with Spark 2.7.5 and i would like to limit the file transfer size.

Do i have to do it in the Spark-Clients itself or is there any possibility to change central on the server?

This setting is not allowed to be changed by the users.

Thanks in advance
