Folder implements FolderInterface

A folder that groups files in a storage. This may be a folder on the local disk, a bucket in Amazon S3 or a user or a tag in Flickr.

This object is not persisted in TYPO3 locally, but created on the fly by storage drivers for the folders they "offer".

Some folders serve as a physical container for files (e.g. folders on the local disk, S3 buckets or Flickr users). Other folders just group files by a certain criterion, e.g. a tag. The way this is implemented depends on the storage driver.
