# documentStorageURL The root URL for all shared documents. ``` var documentStorageURL: URL { get } ``` ## Discussion This property contains the URL `/File Provider Storage`, where *container URL* is the value returned by the method. The container URL refers to an app group container directory used by the `NSFileProviderExtension` extension. You can specify this shared container using the `NSExtensionFileProviderDocumentGroup` key in the File Provider extension’s `info.plist` file. > Note: > While this property is available on macOS 11+, you don’t need to use it when creating a file provider extension that adopts the ``doc://com.apple.fileprovider/documentation/FileProvider/NSFileProviderReplicatedExtension`` protocol. --- Copyright © 2026 Apple Inc.
