I can't think of a reason why you would want to go back to using fat16.
While that's true, I don't like the "you can't" go back idea of it. You understand what I mean? Like, I have the option to go there, but not back? Catch my drift?

If you are upgrading to fat32 to increase the speed of your system than you would not want to us any disk compression software as even the best compression software on the market is still incredibly slow when compared to disk access times of an uncompressed volume.
Excellent point.

This would only be a problem is you had upgraded from a previous version. If you had done a clean install you wouldn't be able to uninstall to a previous operating system anyway. And would you really want to run Win95 again?
Yeah, I had a clean install of Win98, and I wouldn't want Win95 so I agree.

Given that Fat16 has not been the prominent FAT file system for quit a few years you should be able to find new versions of any software that will support fat32 if the version you have doesn't.
Again, excellent point. Thanks for the information and advice. And the helpfile is the Window's helpfile that you can read before converting. I just read it for the hell of it, but if it's old and everything. Again, thanks for the advice. Make's me feel alot better about it.
