I'd like to keep track of every ISO I make of my restore disk. To keep version numbers, and easily identify the different versions. What do I need to do to make the batch listed below call the old version number (from a text file, likely), add 1 to the number, store this to memory as a variable, and write the new version number over the old in the text file, then use the version number variable in the iso file name? This way, if I have multiple revisions of the iso saved, it's easy to tell just what 'version' is most recent/experimental. Thanks, Gai-jin CLS @echo off TITLE Creating ISO Image of Windows XP Professional ECHO.
