Webbvissl.utils.io.copy_dir(input_dir, destination_dir, num_threads) [source] ¶. Copy contents of one directory to the specified destination directory using the number of threads to speed up the copy. When the data is copied successfully, we create a copy_complete file in the destination_dir folder to mark the completion.
