How to create 7-Zip or SFX in DOS?

**cybpsych** · December 16, 2004

guys, i'm dire to enlist your help here ...

is there any1 know how to create 7-Zip in DOS mode?

i've been playing with 7za.exe and working fine on my XP-based PC.

but when i copy over 7za.exe to a DOS-based system, it would not run and stating that '...cannot run in DOS mode' msg ...

7zip is not supported in true dos. you have to use pkzip for that

7z.exe a -r -sfx -mx=9 somename.exe *

this is for creating a sfx with ultra compression in commandline.

but in real dos mode you have no chance extracting/creating a 7zip as eagle pointed out already.

WinRAR has a DOS version of itself (rar32.exe) - which can create SFXes for use with true DOS.

thanks guys, for the explanations ...

i found that 7za.exe stated it's command-line => assuming it can be used under DOS mode ...

i was trying to find alternative to pkzip.exe because of its lack of compression ratio ...

i'll fiddle with rar32.exe and/or rar.exe in DOS mode now

again, thx!

place the attached (extracted) file on the winrar (win32) main dir. with this module you'll be able to create RAR-SFX archives for DOS

was a difficult find, hope you can enjoy it
