FileSystem.DoDirectoryDeepCopyAsync Method

FileSystem DoDirectoryDeepCopyAsync Method

NFX Class Library

[This is preliminary documentation and is subject to change.]

Implements asynchronous deep copy of folders where destination folder may belong to a different file system. The specifics of implementation may be dictated by particular file systems, i.e.: asynchronous strategies for getting file lists may depend on the particular system.

Namespace: NFX.IO.FileSystem
