I dl files via a p2p network. When I open them via WinRar,it gives me an error message that the file cannot be opened as it is corrupted( do not recollect the exact wordings). Is there a way to correct/repair this. It is at times frustrating to find that a file is corrupted esp when the size is a few 100 Mb or more and has taken some time to dl !! Is there a way to find if a file is corrupted in advance ?? Thx in advance.
