Lotus Word Pro Document (.lwp)
The LWP file extension stands for Lotus Word Pro Document, a file format used by the Lotus Word Pro word processing program, part of the Lotus SmartSuite. Developed by IBM, it was widely used for creating, saving, and sharing documents with rich text features, including graphs, charts, and formulas. Although now considered obsolete, LWP files can still be converted to modern formats like Microsoft Word.
