Persistent Property


Xceed.Zip Assembly > Xceed.Zip Namespace > ZippedFolder Class : Persistent Property

Gets or sets a value that indicates whether the folder entry will be persisted in the Zip archive.

Syntax
'Declaration
 
Public Overridable Property Persistent As FolderPersistence
'Usage
 
Dim instance As ZippedFolder

Dim value As FolderPersistence

 

instance.Persistent = value

 

value = instance.Persistent
public virtual FolderPersistence Persistent {get; set;}

Property Value

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.

The value of this property is independent of the Exists property. You can mark a folder as persistent before it exists.

If you assign a value to other properties of this class (e.g., Comment, LastModifiedDateTime, etc.), the folder will be marked as persistent so that the new values are preserved.

The default value depends on the value of ZipArchive.DefaultFolderPersistence, which is false.

Requirements
