DeepCopyTo(FileSystemDirectory, FileSystemDirectory.DirCopyFlags, Int32, Func<FileSystemSessionItem, Boolean>, Func<FileSystemSessionItem, Boolean>)

Performs a deep copy of this directory into another directory that may belong to a different file system. This method allows to copy directory trees between different file systems i.e. from SVN into AmazonS3 or local file system etc.

Declaration
public void DeepCopyTo(FileSystemDirectory target, FileSystemDirectory.DirCopyFlags flags = FileSystemDirectory.DirCopyFlags.Directories | FileSystemDirectory.DirCopyFlags.Files | FileSystemDirectory.DirCopyFlags.Security | FileSystemDirectory.DirCopyFlags.Metadata | FileSystemDirectory.DirCopyFlags.Timestamps | FileSystemDirectory.DirCopyFlags.Readonly | FileSystemDirectory.DirCopyFlags.FilesAndDirsOnly | FileSystemDirectory.DirCopyFlags.All, int bufferSize = 65536, Func<FileSystemSessionItem, bool> filter = null, Func<FileSystemSessionItem, bool> cancel = null)
Parameters
Type Name Description
FileSystemDirectory target

Target directory where the files will be placed. It's name does not have to be the same as the source's name

System.Int32 bufferSize

Copy buffer size
System.Func<FileSystemSessionItem, System.Boolean> filter

Optional filter function
System.Func<FileSystemSessionItem, System.Boolean> cancel

Optional cancellation function. Return true to abort copying
