Unfortunately you have experienced an error when trying to read the RAR files when Extracting or Unarchiving.
The is the most common mistake is by not having a Extractor that cant read the “.rar” file format.
We’ve had good experiences with these unarchiving tools that are readily available and free to use.
Note** When extracting .RAR files, always and only start with the first file, the #1 file. That will unpack all RAR files and will create one master file (folder structure) for your content.
Others Available: WinZip, ALZip, RAR unarchiver, and others. Just do a little search and you’ll be good to go! Learn more on How to Extracting RARS and Zips.
