I got my taste of "full" folders with NT during the early days of DVD programming. The software would write everything into a single directory where it would create at least 3 files per source asset. We were working a specialty DVD that had 100k assets. The software+NT would crash crash crash. The next year the project came through, we were on a newer version of the software running Win2k and performance was much improved using same hardware. I haven't had to do anything with a folder that full in years, but I'd assume it is less of a chore than the days of NT. Then again, it could have gotten better, but then regressed as well. Really, I'm just happy I don't get any where close to that to find out.
