Why in my toribash folder is there files called this:
Fuck you dickhead
I love u stonen
Idk

You have a Gremlin in your computer! :P
Now serious: Maybe if you post what kind of extensions those files have, and where exactly u found them (complete dir path).
(example: somethig.jpg - image, something.txt - text file, etc)
Which extension they have?

it just says its a file

It's done from your computer. If any of your friends have accessed your computer, they probably put it there. It's not included as default in Toribash, that's for sure.

Yeah.

Although, I noticed that sometimes some replays that I watched by clicking on them on forum appear in my Toribash game folder (replays that belongs to some other ppl).

So, since some ppl name their replays in 'strange' way (f*** you di**head.rpl), it could be that. So, if u right click on that file and go to properties you can check. If it has .rpl extension, then it is stray replay.
But size of 0 bytes is strange.

Or... You have a Gremlin in your computer! :P
Or, at least, you have one that uses your computer when u are away. :]

I am the only user on my computer and if my friend comes round and goes on my laptop im there.

That might be the reason that the file is 0 bytes.

Did you try to download a replay with those names?
