How to open an OXT file

You need a suitable software like LibreOffice to open an OXT file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your OXT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a OXT file directly in the browser:.

OXT format details:

Every file has a defined file format, i.e. how the data is arranged in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Knowledge is power - this also applies when dealing with unknown or faulty files. In the following you will find our evaluation of the OXT files:

The OXT file type is mainly used by one program with a specific format. However, the following two file formats are common:

97% of all OXT files use the ZIP format, i.e. an OXT file contains several compressed files. 7 to 37 compressed files are common. File names inside are description.xml, dictionaries.xcu and \META-INF\manifest.xml. You can see the included files and images by renaming the file extension to .zip and then double-clicking it. Most of these files are 85 KB to 6 MB in size. Examples of file names are dict-en-20180601.oxt. Such files sometimes refer to dict, frami, vrtnetworkequipment, office, language, writer, tool, dictionaries, thesaurus, hunspell, latex and open.

All other OXT files (3%) have no uniform format. These files sometimes refer to grammalecte, dictionary, numbertext, turkish, import, czech, libre or pack. If you want to find out what your OXT file contains, drag and drop it onto this page.
