Visual FoxPro is a Microsoft relational database management system and programming language for Microsoft Windows. Its distributable support libraries provide runtime components required by applications created with Visual FoxPro.
An esl file contains a Visual FoxPro distributable support library. A compatible Visual FoxPro application can use the file together with its other application files when it runs.
This format is obsolete and is associated with legacy Visual FoxPro software. It is not normally used by current database or application development tools.
An esl file is not normally opened as a document. On Microsoft Windows, it should remain with the Visual FoxPro application that requires it; the application loads the library as needed.
Visual FoxPro or a compatible Visual FoxPro runtime is required to use the file. Renaming or editing the file can prevent the associated application from running.
An esl file is a compiled support library, so it has no useful general-purpose conversion to another file format. It should be retained in its original form with the Visual FoxPro application that uses it.
If the goal is to reuse data from a legacy Visual FoxPro application, the data should be exported from that application rather than converting the ESL library.
