Specifically, it provides the following features that are not provided by the standard import and export tools provided by WordPress. 1. The standard tool does not export images and other media data. Instead, the importer reads the image URL in the XML and attempts to re-download the file from a remote location. However, this requires that the import source site is public and the media file URL is accessible. If the site is local or private, the media download will fail and only an empty attachment post will be created. This plugin extracts images and other media data and WordPress database information and exports them together in a single ZIP file, eliminating such problems. 2. The standard tool does not export revisions, but this plugin provides export and import functions. 3. The standard tool allows you to select what to export for each post type, but not for each individual post. This plugin allows you to select what to export for each individual post. ### Related Links * [POST MIGRATION:Github](https://github.com/itmaroon/post-migration) ### Third Party Libraries This plugin uses the following third-party libraries: ### FileSaver.js * Purpose: Used to enable client-side file saving functionality (e.g., downloading generated ZIP files in the browser). * Library URL: https://github.com/eligrey/FileSaver.js/ * License: MIT License * Resources : https://github.com/eligrey/FileSaver.js Copyright (c) 2016 Eli Grey.
