The default order that directories and files are in a save/load box is
directories first (in alphanumeric order), followed by files (ditto).

I seem to have done something that alters this - the files and
directories _shown to me in save/load boxes_ are in some other order
(creation/modification date maybe? Since date isn't shown in a save/load
box, I can't verify that).

How do I put it back?

RAM disk is *not* an installation procedure.
