I searched annoyances.org for this and here is the result.
There are other results under the XP forum, but they all pertain to this particular subject.
http://www.annoyances.org/exec/show/article02-101I'll quote the first part of it:
----------------------------------------------------------------------------------------------
By default, Explorer displays uppercase (all caps) 8.3 DOS-style filenames (such as "README.TXT") in a "prettier" format (such as "Readme.txt).
If the filename has more than eight letters (not including the extension), or if the filename contains at least one space, the capitalization is not modified.
(Note: Windows doesn't actually change the capitalization of any files, only the way they're displayed in Explorer.)

Look at the last sentence,
(Note: Windows doesn't actually change the capitalization of any files, only the way they're displayed in Explorer.)
There is a registry setting for this, but it only effects how windows explorer, desktop folders, and windows program's file dialogs, display uppercase filenames and foldernames.
It doesn't actually change the uppercase to lowercase, it just changes the way it looks in windows.
So what is actually changing my all caps folders/files to all lowercase when I transfer files from my windows box to my Zaurus?
