I have my files set to show extensions so I don't waste time renaming them or getting confused. Goddamn windows
I love it how in Linux or FreeBSD how you just type "ls" and it pretty much shows everything.
Too much hidden stuff in Windows.
copy the file into the replays folder in the toribash folder.
e.g. CProgram Files\Toribash\replays
then it will be in the replays option when you press Escape in Toribash.
