What tool do you use to create the hashes in the "update.ver" filename which represents the size, date, version info etc. I couldn't find any info on MSofts site that says a). what tool to use and where to get it. b). What each of the entries in the "update.ver" represents That is each field per line in the file. Some include "SP2QFE" and "SP2GDR" too. I'm on Win 2K and Win XP. Is there a difference in the tool that one uses?
