Exemples

The following code example creates a FileSystemTask as an Executable in a package. The FileSystemTask copies a test folder, which contains two subfolders and a .txt file, to another folder. The folder and subfolders that are the source folders have their attributes set to read-only because the the Attributes property is set to ReadOnly in the code example.
