A solution to error 0x80004005 (unspecified) when you extract zip archives
You may download .zip archives from various sources, which means that corruption is not an issue (there can’t be all of them corrupted!), and still the Windows native unzip utility or even WinRar refuse to extract these archives!
Upon extraction Windows gives this alert:
An unexpected error is keeping you from copying the file. If you continue to receive this error, you can use the error code to search for help with this problem. Error 0x80004005: Unspecified error
Most probably the archive that your programs or Windows are unable to extract, has been
compressed with an algorithm that they don’t support, such as bzip2.
