The LDL file format is associated with Corel Paradox, a relational database management system from Corel Corporation. Paradox was also included in some editions of Corel WordPerfect Office.
These files contain delivered libraries used by Paradox. They are library components rather than ordinary database tables and are generally encountered in legacy Paradox installations.
Open the file with Corel Paradox on Microsoft Windows, or with a version of Corel WordPerfect Office that includes Paradox. An LDL file is normally loaded by the software as a library component rather than opened as a standalone document.
An LDL file is a delivered library, not a database table or document, so it normally has no useful standalone conversion. Keep it with the Paradox installation or application that requires it.
