The shaders are really great - I spotted the extra folders and just deleted them - no problem, but thanks for fixing the archive. A lot of people who use the ZIP that comes with Windows do the same thing and it does get tiresome to have to delete all the empty folders. If you use a better ZIP program, the empty folders will be disregarded when you create the archive. I use Power Archiver and love it (I used the freebie for years, and finally decided the guy who made it deserved the 15 bucks cause it was so great) - it will make smaller zips than Windows too! and you can view the contents as a list or as a directory tree whichever you prefer. Lots of other nice features too, and reads almost all compressed formats.
