What I am trying to do is bypass WinRAR SFX EXE 4GB limit so the exe can only be up to 4GB in size because of 32bit, the .rar file is 18GB and needs to be extracted in the same place as the files in the SFX EXE file, the .rar file is not in the WinRAR SFX EXE but next to it.

So was thinking of get WinRAR SFX EXE to run a bat file then in the bat file tell it to extract the rar file maybe with WinRAR or something or add a comandline version for rar in the SFX and tell it to use that, what you think, it a shame a WinRAR SFX EXE can do it itself..?

Do you think its possible..?
