Sentence:  If you "uncook" a file that isn't "cooked" you will just mess it up (and I don't know of any way to fix it then) - so <WSD>uncooking</WSD> should be used with caution (I'd suggest never over-writing the original file). 
Meaning of the word marked with <WSD> tags:  To repair a file (specifically an MP3 audio file) that has been damaged ("cooked") by being converted through a text format and having line breaks applied to it.
