Table 5.1 in this article, and some surrounding description,
indicate that ntfs converts to upper case when doing directory
inserts, so if you want to optimize the disk order for the order
processed by directory entry it seems toUpper would be a better
choice.

A $UpCase Maps lowercase characters to their uppercase version,
used when inserting files in a directory.
Maybe a more efficient ordering for a folder could be achieved by
create zero length files for everything, then read back the ntfs
directory entries, and use that order to expand the files.
