i have downloaded some rar files in part but when i tried to join it it gives an error " CRC data failed;The volume is corrupt . it happens in many files which i downloaded . i re downloaded also but the problem persists . what to do?

What program do you use to unzip?

i have used winrar winzip both but same problem

It looks like those files are corrupt. Where are those files from?

i have downloaded it through rapidshare.

IF there is no copyright issue involved, post a link, I'll download the file, and we'll see, if I have same issue.
