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.
This format was created by Nokia for use in its proprietary phones. A bitmap image was used to transfer image files between devices over a wireless connection. It was mainly used when exchanging multimedia text messages that support inserting pictures.
