ODT file format
Microsoft Office 2007
Microsoft Office 2010
Twenty years ago, Sun Microsystems developed the Open Office, which included the ODT. It is open-source software that can serve as a free alternative to Microsoft's Office suite of products. The Open Office is compatible with several Microsoft document formats, and it's offered for free. The word processing element of Open Office is the writer application that produces ODT files.
OpenDocument text file format in both proprietary and free software stands alone. A Technical Committee (TC), an affiliate of the Organization for the Advancement of Structured Information Standards industry consortium, developed a web-based office suite. ODT files are created with synchronized multimedia integration language and scalable vector graphics, all of which have gone through the World Wide Web Consortium's Web Accessibility initiative standards.
