What is an SXW file?
An SXW file is a legacy text document format associated with Sun Microsystems' StarOffice and the early versions of OpenOffice.org Writer (prior to version 2.0). It relies on the OpenOffice.org XML format, structuring data within a ZIP-compressed archive that contains XML files defining text, styles, and settings. This format was the direct technical precursor to the ISO/IEC 26300 OpenDocument Format (ODT) and shares a similar XML-based architecture, making it highly compressible and open for parsing.
How to open an SXW file
Native support for SXW is absent in default OS installations but is standard in open-source office suites. LibreOffice Writer and Apache OpenOffice are the recommended applications for opening and converting SXW files to modern formats like ODT or DOCX. Microsoft Word can usually open these files if the appropriate ODF converters or compatibility packs are installed, though layout discrepancies may occur.

What is an RTF file?
The Rich Text Format (RTF) is a proprietary document file format with published specifications developed by Microsoft Corporation in 1987 for cross-platform document interchange. It encodes formatted text and graphics using 7-bit ASCII characters, utilizing a structure of control words, control symbols, and groups to define formatting properties such as bolding, italics, and fonts. Unlike binary formats, RTF is human-readable and was designed to facilitate interoperability between different word processing software and operating systems before the standardization of XML-based formats.
How to open an RTF file
Due to its design as an interchange format, RTF possesses native support across almost all major operating systems without requiring third-party installation. Microsoft Windows opens RTF files natively with WordPad or Microsoft Word, while macOS utilizes TextEdit. For Linux users or cross-platform consistency, LibreOffice Writer and Apache OpenOffice provide robust handling of the format's styling attributes.
