The Shutterfly Folder API provides access to a user's folder content, including folder URLs. Information such as folder title and the folder's album list are expressed in Atom XML.
Shutterfly users group their albums in folders. If nothing else, each user should have a default folder like "My Albums". The Album API lets you enumerate the user's albums, without regard to how they may be grouped in folders. Alternatively, the Folder API lets you enumerate the user's folders, then enumerate the subset of albums belonging to a given folder.
Shutterfly does not support nested folders, which keeps the folder hierarchy simple: it is never more than one level deep. The user contains one or more folders; each folder then contains zero or more albums.
