Is there any simpler way to get a real path of a file or folder, even if the path, to start from, contains unfortunately uppercased parts? Filesystem object doesn't even have such a function, it keeps the casing as was passed to it.

The one way I know is to use the 3rd parameter to adir(), which means recursively checking each level of the path and then reassembling it. Not that I don't have the time to do it, now I have, and (even worse) I have a strong deja vu, I think I already wrote such a function once but can't remember what I called it...

Still, is there a simpler way?
