when i extract it , WinRAR says "the archive format is unknown or is damaged". im sure this problem is not due to rar5 algorithm, so could it be damaged archive , can someone check this ? btw,im using WinRAR 4.2 .
It may or may not be the fact that your version of WinRar is a bit outdated... but I'm siding with the fact that it is You SHOULD at least be on version 5 methinks. I for one am on version 5.21 to be exact
just moved on to WinRAR 5.21 and extracted the archive . No errors at all. i guess it was because of the outdated version of winar.
