Question

As far as I know, FileInformation and FolderInformation are both created through FileInformationFactory. But FileInformationFactory can only return the sub-folders or sub-files in the folder, not the folder itself. So if I want to get the FolderInformation for the top-level folder, like KnownFolders.PicturesLibrary, it seems no way to do so.

Answer 1

Usually pictures library is not itself a folder in the traditional sense of a folder. It is just a collection of locations you want to include in a logical entity called a library. And these locations need not even be in a proper hierarchical order. So a library probably doesn’t have properties like a folder does.
