Quick Solution / Fix for WinRar CRC failed : Volume is Corrupt error
Winrar shows CRC error and you think you need to download those file parts again ? well , you can skip that as I present a really easy solution , although this does not works all the time but still it will give you a good chance of not downloading those lengthy rar file parts again .
A sample error with a zip file , similar error pops up for multi part RAR files too.
All, you need to do is try extracting the same file with 7zip , just download 7zip and after installing the proper version (32bit or 64bit ) try extracting your files and this time it will extract in most of the cases , so don’t waste your money in buying advanced RAR recovery software for what you can do for free 
Have fun!

WinRAR CRC failed is a common error which we find while unzipping any files and gives us feel of total data loss. BIG Relief NOW…. Bravo..
