W60 is a proprietary document file format developed by Corel (formerly WordPerfect Corporation) for the WordPerfect 6.0 word processing suite. It was primarily used for creating and storing complex text documents featuring advanced formatting, tables, and integrated graphics on DOS and early Windows platforms. Now considered an obsolete legacy format, it is generally safe for modern systems, although viewing the content typically requires specialized conversion software or older word processing applications.
