	FileAttributes targetAttributes
)

Parameters

fileOperation
Type: ITHit.FileSystem.WindowsFolderOperation
The operation to perform.
targetUserFileSystemPath

parentWindow
Type: SystemIntPtr
A handle to the window that the copy hook handler should use as the parent for any user interface elements the handler may need to display. If FOF_SILENT is specified in operation, the method should ignore this parameter.
flags
Type: ITHit.FileSystem.WindowsFolderControlFlags
The flags that control the operation FolderControlFlags enum.
sourceAttributes
Type: System.IOFileAttributes
The attributes of the source folder.
targetAttributes
Type: System.IOFileAttributes
The attributes of the destination folder.

Return Value

Type: TaskFolderOperationControl
Value that indicates whether the Shell should perform the operation.
Remarks

To allow or forbid Shell from performing operations, follow these steps:

  1. Derive your class from one of the [!:StorageProviderCopyHookBase] class descendants. Add the GuidAttribute, ProgIdAttribute and ComVisibleAttribute attributes to your class. You do not need to implement any methods in your class.
  2. Register the COM server in your Package.appxmanifest (in case of packaged app).
  3. To register a copy hook handler for cloud folders, call the [!:ShellExtensionRegistrar.RegisterHandler] passing "CopyHook" as a handler name. Note that unlike other handlers, CopyHook must be registered in all cases, regardless if your app is running with or without identity.
  4. Implement the GetFolderOperationControlAsync(FolderOperation, String, IntPtr, FolderControlFlags, FileAttributes, FileAttributes) with your logic.

CopyHook functionality does NOT require package or application identity.
