There are many bat2exe tools out there, or more appropriately a wrapper (not a compiler anyhow). But I think mine is the one that its resulting exe behave like a proper cmd apps. It's based on modified 7zip SFX module. It's called portabat


  • Simple editing, just open it with 7zip and put your batch files there.
  • Your batch files always executed regardless Windows policy to disable command prompt
  • Can be passed command arguments 
  • Behave as multi-call batch launcher based on its SFX name (matched to .bat/.cmd name inside)
  • Your batch files always executed regardless Windows policy "disable command prompt"
  • Have standalone reg which bypass Windows policy "disable registry tools"
  • Your other executables / batch files in the \bin sub-directory will available in PATH lookup 
  • Executed at the "correct" working directory
  • Do not spawn new cmd box if called from existing cmd box (always reuse existing console)
  • Can be called (and have the correct working directory) from anywhere inside PATH environment
  • Your echo %%~nx0 is echo %SFX%
  • Your SFX path is %SFXPATH%
  • Your extraction path is %~dp0
  • Largely compatible cmd.exe from ReactOS
  • Can handle inf files as well (DefaultInstall entry)
  • If cwd file exist in the archive, current directory will be temp. extraction path
  • Be sure to always reference other files/folder in archive with %~dp0 prefix
  • Batch filename execution order (prefer .bat over .cmd)
  • Compatible with XP or later

What's Bundled?

Inside the tiny 350KB executable there is more than 70 tools (curated from the internet) for different area of interest. Sources are available with exception for MS forfiles, rvkroots and updroots). All tools are LFS aware and with exception for gsar and busybox are Unicode filename aware.


cmd.exe : Batch processor from ReactOS which at runtime automatically override Windows CMD. Batch while considered lacking as a language is still good for file processing. Recommended to call it as %COMSPEC%

busybox.exe awk : Posix awk from busybox for heavy-duty text processing that goes beyond sed and grep

autoit3.exe : Old GPL version of AutoIt 3.0.102 is one of most popular UI automation language, while its role in assisting batch task may minimal, it's still important addition in the Windows environment.

All those three intended to run script file .bat/.cmd, .awk and .au3 respectively

partfile.exe : File partial copy/peek and split
partfile foo.iso bar.part 20000 64000
copy 64000 bytes of foo.iso starting from offset:20000 into bar.part
partfile foo.iso bar.part - 64
split foo.iso into 64 pieces of bar[n].part
partfile foo.iso bar.part - 1000000
split foo.iso into pieces of 1000000 bytes bar[n].part

ppx2.exe : Parallel processing similar to xargs, works via piping. Note that it doesn't work (in parallel) if piping feed and done inside for loop.
dir /S /B /Ahs-d /Od *.png | ppx2 -P 8 -L 1 gdipconv "{}" "{}.jpg"
dir /S /B /Ahs-d /Od *.png | ppx2 -P 8 -L 1 %COMSPEC% /c gdipconv "{}" "{}.jpg" ^&^& del "{}"
Convert all png to jpg image at 8 parallel task, notice the result will have .png.jpg suffix
