I have the archives that I downloaded:
2MGF&DPNA.part1.rar
2MGF&DPNA.part2.rar
2MGF&DPNA.part3.rar
2MGF&DPNA.part4.rar
2MGF&DPNA.part5.rar
Everywhere write that utility unrar
unpacks automatically a chain of archives.
But when I entered
unrar x '2MGF & DPNA.part1.rar'
I saw that only one archive was unpacked.
It turns out I beleive the utility does not work as it should, if I unpack after it the second archive manually, then I just have to replace the files!This is not at all what you need!
I need a clear instruction for arch Linux, I beleive 7z also does not know how to unpack multi-archives.
