What is a W51 file?

W51 files mostly belong to WordPerfect. WordPerfect 5.1 documents have the W51 file extension.
This file type stores text along with layout and formatting instructions that were built into the WordPerfect 5.1 word processor.
When you open a W51 file, you will see that it carries special formatting codes used for margins, styles, and page layouts which are unique to WordPerfect's internal document design.

Opening the File: Use WordPerfect version 5.1 or a later version that supports legacy formats.

Editing: Compatible programs like LibreOffice may convert or open these files, though the best results come from using WordPerfect itself.

More Info: Visit the WordPerfect website for details.

FilExt.com note: W51 files highlight an older, structured approach to document formatting not found in basic text files.

W51 file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. If there are problems opening a file, you must first determine the file format used. Our examination of the W51 files comes to the following conclusion:
