Using ReadDirectoryChangesW

ReadDirectoryChangesW reports any changes to a folder (file being renamed, removed, etc).

Sometimes it returns long filenames, sometimes short.
Sometimes it's impossible to convert between long and short filenames (notably when a file is deleted).
Sometimes the short filename for a file changes without actually touching that file at all.

Is it possible to actually use that function reliably?

| An application would need to keep a cache of both short and long | file names to match them up when the notification is received.

Easy.
