Files that contain the .abw file extension are most commonly associated with the AbiWord word processing software application. AbiWord is a free word processing software that has been created by the AbiSource software community.
The ABW file format is the default document format for the AbiWord word processing software and the format is based on XML. The ABW file format allows for advanced document layouts, rich text formatting, lists, tables, images and footnotes. ABW files are similar in nature to Microsoft Word DOC files, however, unlike Microsoft Word files, the AbiWord program can run on almost any computer operating system.
