It's no wonder 7-Zip is so popular with changes like this. Pure genius! :-P

Calculate back how many bugs must have been in 7-ZIP 4.2xx :lol3:

But it worked for me ...

P.S. The file 7ZA.EXE included is packed with UPX 2.03. Well, we all (now) know that later UPX versions (e.g. latest 3.01) support LZMA from 7-Zip. So, a quick upx -d 7za.exe && upx --ultra-brute 7za.exe shrinks it from 753,448 bytes to 610,520 bytes (quite a difference!).

IIRC, yes, but not RAR or ARJ, only .tar.gz (-tgzip), .tar.bz2 (-tbzip2), .tar (-ttar), .zip (-tzip), and the default 7-Zip (.7z) format.

RAR is shareware, but ARJ (shareware) is free for non-commercial use (I think). UNRAR and UNARJ are free/open source, though.

The DOS version is based on p7zip, which is a port of the standalone 7za.exe, not of 7z.exe. 7za packs and unpacks 7z, ZIP, GZIP, BZIP2 and TAR files, and for Z files it unpacks only.

There a few more notes I should mention:

7-Zip (7ZA.EXE or P7ZIP.EXE) can now choose a filetype based on .ext of the archive being created. So, you don't have to use -tzip or -t7z or -tbzip2 but instead "7za a blah.7z *" or "7za a blah.zip *" or "7za a blah.bz2 blah.tar" instead.

P.S. For .7z format, defaults are (according to 7-zip.chm from Win32 cmdline version) -mx=5 -ms=on -m0=lzma. So, you only need to use "-mx=9" if you want max compression, or "-m0=ppmd" if you'd rather use a different algorithm (but PPMD requires more memory).

7-Zip (Win32) can create ("compress") only: 7z, ZIP, GZIP, BZIP2 and TAR.
Free UNRAR for DOS is at http://www.rarlab.com/rar_add.htm.

@ Steve

"7za -w" fails in pure DOS

Unfortunately, p7zip (or 7ZA + HXRT) refuses to let "-w" (temporary work dir) work b/c of LFN issues (tries to make "blah.zip.tmp" or something dumb like that). Is there a possible way to make HXRT translate filenames like this (which seem fairly common in the Windows world) to 8.3 ?
