Oh, one more thing. I asked on the 7-zip forum if nested archive extraction could be added to the 7z.exe command line. It's something the developer has plans for, but of course, no time frame If anyone comes across a tool that does allow nested archive extraction from the command line, it would be good to know. My ideal solution would be a modified GWT. I haven't tried the XP tricks to get httpdisk working, but I will if time allows. Thank you jaclaz, JFX and Sp0iLedBrAt.
