A WPS file is a document created with Microsoft Works word processing software. It contains document elements similar to a Microsoft Word (.DOC) document, but does not include advanced formatting options and macros that a Word document may contain.

WPS file open in LibreOffice Writer 5 Microsoft Works 9 was the final version of Works and the software was discontinued in 2010. However, Windows users can still open WPS files created by Works versions 6 to 9 with Microsoft Office applications and "Microsoft Works 6–9 File Converter" installed. WPS file can also be opened in LibreOffice. The macOS (Mac OS X) version of Microsoft Works was discontinued after version 4.0. Therefore, most modern Works documents cannot be opened using Works for Mac. However, WPS files can be opened in macOS using NeoOffice 2.2 or later, which includes the "libwps" library. On Linux systems, WPS files can be opened using OxygenOffice Professional or another variation of the OpenOffice.org suite that includes the "libwps" library. Some Linux distributions may also include a program called wps2odt, which uses libwps and can convert WPS files to .ODT files. A package called "writerperfect" may also include wps2odt if the appropriate version of libwps is available. Also, the Writer program included with the free LibreOffice suite is another program that supports WPS files. It is a great alternative for Windows, macOS, and Linux users. NOTE: The WPS format was discontinued by Microsoft in 2006 and was replaced by the standard Microsoft Word ".DOC" format.
