Beispiele
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 are copied because the action to perform, as indicated by the Operation property, is set to CopyDirectory.
