What is an ABW file?

AbiWord Document

Developed By
AbiSource
Initial Release
1998
MIME Type
application/x-abiword

The ABW format is the native document file type for AbiWord, an open-source word processor originally developed by SourceGear Corporation and later maintained by AbiSource. Unlike binary formats, ABW utilizes a plaintext XML (Extensible Markup Language) architecture to define document structure, formatting, and layout settings, making it human-readable and parsesable by standard text editors. The file schema maps formatting tags to document content without binary obfuscation, though it lacks the support for complex macros and embedded objects found in Microsoft's OLE-based formats.

How to open an ABW file

As an XML-based format, ABW files are natively supported by the AbiWord word processor across Windows, Linux, and macOS platforms. For broader compatibility, the LibreOffice suite and Apache OpenOffice can import and render ABW documents with high fidelity. Because the underlying structure is plaintext XML, users can also view the raw code using advanced text editors such as Notepad++ or Sublime Text, though this will not render the visual formatting.
