[HowTo] Unpack "Corrupt" WinRAR Things ;P

I Was Bored,And i think some of you got The problem,if they got CRC Fail or Something with WinRAR.This is,if Keep broken Files not work in WinRAR.

First,Copy the rar.exe from youre winRAR folder,to C:\

Then do the RAR u want to unpack in C:\ too.

Open "CMD".After it Write : cd C:\
Then press enter.After u did that,Write: rar e -kb "filename"
Without " ".

Then press enter and hes unpacking it^^.
Now u unpacked it =D...

if the code doesnt work,try : rar.exe e -kb "filename"

Some Words are BAd english,Sorry im from Germany ;)

I know it, but it not work if I do this whit a 6 GB WinRAR Archive, then I can't install it.
