What “reviewed” means on this page
  • Format fit: whether the “what is this file?” description plausibly matches common real-world use of the extension, including category, typical MIME types, and aliases.
  • Opening paths: whether Windows / macOS / Linux steps read plausibly for current OS dialogs and default apps. Not every step was tested on every OS version.
  • Security framing: whether risk notes match the extension class (for example executables vs plain data) and whether affiliate wording does not contradict the security section.
  • Sources and further reading: external links should point to vendors, standards bodies, or other primary references where possible; not every detail is individually sourced.
  • Limits: this is clarity and safety-messaging QA, not a guarantee that every statement is exhaustive or that every binary you download is harmless. Pages without “Reviewed by” have not been through this editorial pass yet.

OS-specific troubleshooting

What is a .ODT file?

.ODT stands for OpenDocument Text, a file format used primarily by word processing applications. It is part of the OpenDocument Format (ODF) for office applications, which is an open standard for document exchange.

Background

The .ODT file format was developed as part of the OpenDocument Format, an open standard supported by the Organization for the Advancement of Structured Information Standards (OASIS). It was designed to provide a free and open alternative to proprietary document formats like Microsoft Word's .DOC and .DOCX. ODT files are typically created and edited using open-source software like LibreOffice Writer, but they can also be opened and edited in other applications, such as Microsoft Word, Google Docs, and WPS Office. This flexibility makes the ODT format popular among users who need a versatile and accessible document format. The format supports a range of features, including text formatting, images, tables, and styles, making it suitable for both simple and complex documents. ODT is particularly favored in environments that prioritize open standards and interoperability, such as government and educational institutions.

Common MIME types: application/vnd.oasis.opendocument.text
