Question

FolderInformation‘s methods/properties are nearly the same with StorageFolder‘s.
I can’t figure out why WinRT api provides FolderInformation and StorageFolder as well. If I assign the list created from FileInformationFactory.GetFoldersAsync() to an ItemsControl, does it differ from the listed created from StorageFolder.CreateFolderAsync() ?
The document says the FolderInformation provides synchronous access, but I don’t know when the issue would happen.

The one drawback I found in FolderInformation is it could only be created from FileInformationFactory. So I think it’s impossible to create a FolderInformation for the KnownFolders.PicturesLibrary.

FolderInformation lets you act on the Folder itself (as in move it, delete it, rename it etc.)

Whereas StorageFolder lets you act on the contents of the folder (as in create a new file in the folder, create a new sub-folder in the folder, get all the files from the folder etc.)
