Question: what is CRC ? i try to extract files from a rar file i made & it gives me a CRC error ?!!? 

Answer: 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.\nIn your case, the codes don't match>i.e. the file is corrupt.\n\nThere are programes that can (at least they try to) repair broken RAR archives. Look up with Google after "rar recovery software".\n\nBetter redownload/recopy.
