What is an ODT file?

Apache OpenOffice is a free open-source alternative to Microsoft Office. To save money yet still produce Office-compatible documents, some students and professionals use OpenOffice in place of Microsoft Office.

Writer is OpenOffice's equivalent to Microsoft Word. It allows users to write and format personal and business documents, such as resumes, letters, essays, and research papers. Writer saves users' documents in ODT files, which are similar to Word's DOCX files.

ODT files are formatted using the OASIS XML-based OpenDocument standard. This standard is used by OpenOffice, LibreOffice, and other variants, all of which save documents as ODT files.

NOTE: Apache OpenOffice was formerly known as OpenOffice.org.
