This method of splitting allows you to split a single PDF into multiple files based on the bookmark hierarchy and bookmark levels. This can be particularly useful when bookmarks are based on the sections and structure of your PDFs.

5. Choose how the filename is to be created by selecting an option from the Make the target filename by adding list, entering a starting number if required.
