Note: if you want to add more file extension, you need to follow these steps:

1. Add file extension to layer 7 protocol:
/ip firewall layer7-protocol add name="XXX" regexp="\\.(XXX)"

2. Add file extention to firewall:
/ip firewall mangle add action=mark-packet \
chain=prerouting comment="XEX MARK PACKET " disabled=no layer7-protocol=XXX new-packet-mark=XXX passthrough=no

3. Add file extension to Queues Tree:
/queue tree add name="XXX" parent="LIMIT FILE EXTENTION" \
packet-mark=XXX limit-at=0 queue=default priority=1 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s
