The EndNote Library File (ENL) is a proprietary database format developed by Clarivate for the structured storage of bibliographic references. Researchers and academics primarily use this format to organize metadata, manage citations, and generate formatted bibliographies for scholarly publications. While the file itself is considered safe, it serves as a central index that must remain paired with an associated data folder to ensure database integrity and access to stored attachments.
