All I know is that arc-mode could not handle certain archives that I could handle with a 7z.exe downloaded for comparison. I then researched this issue and found out that those archives used a newer format that the Free Software variants of 7z did not support. In particular, the variant installed on fencepost didn't support it. And the reason was that the newer formats used code that wasn't Free Software and whose sources were not available even under non-Free licenses. > 2.

If we must, it should be a distant second or third alternative to `zip'.
