A FolderPersistence value indicating whether folder entries will be persisted by default in the Zip archive. By default, FolderPersistence.NotPersisted.
Remarks
The Zip specification doesn't require folders to have their own entries in the zip file, especially if the folder is only there as the parent of an item. For example, in the entry for the item "FolderA/FolderAA/File1.dat," the existence of FolderA and FolderAA can be inferred from the path. Having folder entries in the zip file for them is redundant and only increases the size of the archive.
Requirements
Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
