Problem:

I have a file in Toribash>Custom>Tori folder which seems more like a sound-track and i can't delete it.It says the file is open in another program.It seems useless and also it seems a weird file

Things i've tried:

I've tried restarting my pc and not opening toribash but still it shows the same error.It doesn't seem to be opened in another program.
I didn't reinstall toribash yet because i'm too lazy to reserve my important stuff in a folder and i think there would be a better way to solve it out.
