What Is an OXT File?
A file with the OXT file extension is an Apache OpenOffice extension. They add features to OpenOffice applications, such as its Writer word processor, Calc spreadsheet program, and Impress presentation software. You can download OXT files from the Apache OpenOffice Extensions page.
How to Open an OXT File
OpenOffice can open an OXT file via its built-in Extension Manager tool. For v2.2 and later, you can just double-click or double-tap the OXT file to install it. Otherwise, here’s how to manually install OXT files in OpenOffice: OpenOffice can open an OXT file directly, but it also supports loading the extension from a ZIP file. This means you don’t necessarily need to extract the file from its archive if that’s how it was downloaded. OpenOffice can also open extensions that end with the UNO.PKG file extension. That said, some OXT files are downloaded within ZIP or other archives because they include more information or other files that you need to do something with. For example, some ZIP files have a PDF “help me” document, fonts, and other relevant data that goes along with the extension. OXT files should also work with LibreOffice and NeoOffice.
How to Convert an OXT File
It’s unlikely that there are any file converters available that can convert an OXT file to a different file format, because it’s meant primarily for office suites like OpenOffice. Other programs use their own file formats for extensions (e.g., XPI for Mozilla products).
Still Can’t Open It?
The OXT file extension is spelled a lot like some other ones, such as POTX, making it easy to confuse them with each other. This is the primary reason a file won’t open with OpenOffice’s Extension Manager tool: because it’s not really a compatible add-on. If you double-check the file extension of your file and find that it really reads as .ODT instead of .OXT, what you really have is a text document that can only open with word processors. OTX is another that looks a lot like OXT, but actually belongs to a file format that goes by the name “theWord Encrypted Old Testament Text Module.” OTX files store an encrypted copy of the Bible’s Old Testament for use with the program theWord. If it’s not already clear, make sure to check the file extension of your file. If it’s not an OXT file, then research the file extension on Lifewire or Google to see if you can find out which programs can open or convert it.
