append_files Method
Adds specified files to an existing archive.
Syntax
def append_files() -> None: ...
Remarks
All files contained in the files collection will be appended to the archive specified by archive_file.
When append_files is called, only those files which are to be added to the archive must exist inside the collection. Note that if you call scan or extract, you must empty the collection before adding files to the collection to be appended.
After the file is added, the collection will be updated appropriately.
This method may only be used to add files to an existing archive. To add files to a new archive, the include_files and compress methods should be used.
