You mean with or without LFNs enabled? I did notice that it doesn't like truncating long file names (like Info-Zip does, thankfully). Not sure if that's really a bug, just a minor inconvenience.

I've not had lots of motivation to mess with it too much lately. Always distracted by other things. I tried to (very roughly) mention certain flaws here as a kinda raw TODO list, but it will probably take a while before I polish it off.

In any case, 2012-08-20 was the very first initial compile, the one with *nix-only slashes, hence I would suggest testing p7z9201-latest.zip (symlink to latest, naturally), which is currently from 2012-09-03. It does unpack subdirs correctly for me (when using 'x' command). But I don't claim it's totally stable or perfect (by far) yet.

P.S. Yes, do feel free to use 7ZA.EXE + HX, nothing wrong with that, I've got that installed too. But I've never (and don't want to!) tried to recompile that Win32 console version. Perhaps Japheth knows a semi-painless way, but I doubt OpenWatcom is up to any of it (without lots of source tweaks).

P.P.S. If you just want to unpack, use 7zdecode (e.g. from LZMA SDK).
