rar file repair()

I got a rar file that is corrupted. Cannot be open. Any way to repair it and open?

 

I would try using WinRAR to repair the archive.

Try using another program to open it (e.g. winzip). On the 7 zip forums some people are alleging that there is a problem with the 7zip decoder when used on files 7zip created but I don't know if that is true as not tested it myself.

Another free program you could try to open it with is peazip. That might work also if others don't.
