About any sane modern archiving tool can read TAR archives. And most of them understand gz/xz/bz2 compression. You could have used any of that to unpack Cygwin to get a bootstrap environment, then use that environment to unpack the tar with all permisisons restored. Alternatively, RAR can add/restore access data. -- With best regards, Andrey Repin Saturday, April 4, 2015 21:48:51 Sorry for my terrible english... -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
