I ended up extracting all the files by selecting all with extract /*, then compressing all folders
@echo off
for /d %%a in (*) do (7za.exe a %%~na.exe -mmt -mx5 -sfx ".\%%a\*" & RD /s /q %%a)
pause
And by the way i downloaded the 7z cmd line standalone and library for self extract and placed them in the same folder.
I saved over 4GB in space in my development folder. :)
