I have a few crappy replays i would like to dispose of

Navigate to your Toribash folder, go into the replay folder, and delete away.

Go to hardrive folder.
Go to games (for me) or wherever the folder Toribash 3.86 is.
Go to the folder data (or replays i forgot if it seperate)
There should be .rpl files.
All you do is the usual right click then delete stuff.

Thanks
