How do I ID files as corrupt?

[deezpopz]

Just got Limewire, but I am wary of corrupt files but I'm not sure how to ID them. My friend said that you can get Limewire to automatically ID a file as corrupted as soon as you start downloading it, but where do I go to activate this option? A little warning did pop up saying that Limewire suspected a file was corrupt and did I want to continue downloading it? I checked the "always use this response" box and said no, but then I accidentally clicked on the same corrupted file and it didn't tell me to stop or identify it as corrupt. How can I get Limewire to say its corrupted? A million thanks in advance!
