ODT is one of the options for the text file format, which was in little demand and gained relative distribution only in 2014, when Google Docs began to use the ODF format. It takes its name from the OpenDocument Text Document, and is used in office programs that are based on utilities like Open Office or LibreOffice. The open standard ODF (OpenDocument Format) was created by the OASIS community and was intended for the free creation, editing, storage and exchange of office documents. Within its framework, the ODT format also allows the use of databases, presentations, images, tables in text files.
RTF is one of the most common text formats that has a long history. After all, it was developed back in 1982 at Microsoft. The name of the format is an abbreviation of the English Rich Text Format File. Compared to DOC, this is a more universal format that can be used by almost any, even the simplest, text editors. Another of its features is the ability to transfer text between different programs, if the operating system provides the function of export / import of RTF files. Users also appreciate RTF for the fact that such a document can only contain text, without additional heavy macros.
