The Auto Rename feature allows users to automatically rename PDF files based on the document's content. This is useful for users who need to batch process or archive large numbers of PDF documents. For example, in academic research, users may need to rename PDF files based on thesis titles for better organization and management; in enterprise document management, users may need to rename PDF files based on contract numbers for tracking and auditing. Additionally, this feature can be used to rename PDF files based on metadata such as author, creation date, or keywords. By auto-renaming, users can ensure standardized and consistent naming of PDF documents and easily manage and distribute them.
