This module allows content editors to easily replace the source files associated with file-based media types (like "Document"). The replacement file overwrites the existing file, keeping the same filename and path, which is usually what content editors want to do when performing a file replacement. This module operates on the media entity level, meaning the file replacement is done by accessing the edit form for a media entity that has a file source field on it. If you're using Drupal's media module for document management, then this is what you want.
