Thanks for this hint.
The only keys which seem to work for an non-existing file seem to be:
NSURLNameKey
NSURLIsDirectoryKey
NSURLIsRegularFileKey
NSURLIsSymbolicLinkKey
NSURLIsVolumeKey
(I did try many, though not all).
There is more info in the bookmarkData: like full path (this would be much more
useful than just the NSURLNameKey), NSFileSystemFileNumber (probably not very
useful in this case) and others.
Kind regards,
Gerriet.
