If you want to export your Bridge Filters config, copy / paste this into the terminal, and then copy / paste the output into a text editor:

/interface bridge filter export

Or you can export it to a file that can be dragged + dropped from Winbox, or copied by ftp:

/interface bridge filter export file="myBridgeFilters"
