I want to EnumerateFiles, that is, create a list of files that match a wildcard, on a drive or branch of it. I can do that fairly easily with code I've already got. It works reliably in most cases.

The exception cases are when Windows has had some form of restriction applied using its ACL security feature. The EnumerateFiles procedure uses FindFirst, FindNext and FindClose and can access the file attributes of the file/directory that it comes across. The mere file attributes don't return enough information about the accessibility of a given directory for me to avoid trying to change to it when I'm not permitted by its ACL settings.

How can I obtain the ACL properties of a given file/directory so that I can be more fully informed?
