Default [Q] twrp install galaxy note pro 12.2

I'm trying to install the new version of twrp that was just released yesterday for my note pro 12.2, WiFi.

I'm using the Odin method.

When I download the twrp file to my windows p.c., there is no file extension so it doesn't show up in Odin.

Am l to simply rename this file? And what tar.md5?

Also should I use the PDA button when flashing the twrp file in Odin?
