text: what is crc ? i try to extract files from a rar file i made & it gives me a crc error ?!!?   crc stands for cyclic redundancy check (or code); it is a code put after a somehow modified file, such as when you apply the inverse of that modification you be sure to have obtained the same file. in your case, the codes don't match>i.e. the file is corrupt.  there are programes that can (at least they try to) repair broken rar archives. look up with google after "rar recovery software".  better redownload/recopy.
