How come my replay folder is full of replays, and I cant view any new ones I add or old ones?

How are you adding the replays?

Another way to view any replay without having it in your replay folder, is to right click on it, then go properties and make it open with Tb.exe.

That way you can simply double click on any replay no matter where it is and it will play it.

But, it takes more time than usualm:/
And I download them, move them to my replay folder then done
