Thanks jrzycrim, I found what I was looking for in one of the docs. Below is code for a batch script which will automatically compress all .SYS files in a directory into .SY_ files with LZX compression. One caveat, it only works if the path has no spaces in it. If you can figure out a way around that, let me know. @echo off
rem Compressing Driversfor /f %%i in ('dir *.sys /b /s') do makecab /D CompressionType=LZX "%%i"
