"add to..." "add to .7z" in context menu

  • Why do "add to" and "add to file.7z" appear in context menu, if the file already is in a packed format? It would be more (joe average) user friendly imho, if these menu items don't appear, if a file is a compressed format.

    If someone really wants to recompress (I don't know a reason why), he can rename it or whatever.
