Need to send a doc in odf - how do I save with the extension in ODF?
I need to send a document to the Inland Revenue and they will only accept a document in odf with the extension odf. But LibreOffice saves with the extension as fodt, how do I save with the extension in ODF .
How do I save the file, as it does not show in the list offered? There are many other extensions like odt, ott fodt etc.
Either their requirement is bad, or you don't understand it correctly. Normally, it isn't an extension what matters, but the file format. Thus, which file format do they require?
I doubt that any governmental agency would require .odf files: there produced by the Math component of LO. What would they do with a tax-payer-provided mathematical formula?
Read @gabix's comment and explain as accurately as possible what is required.
