I think Wordpress uses .mo files. What does this mean? Why?

---

Wordpress uses GNU gettext method of providing localized translations. This is a pretty common method, with support built in into PHP and many tools (such as poedit) are available to aid translators in working with this format.

Using this method usual means your translatable natural language is wrapped inside a _() function call, making it easy to extract for translation tools.

.mo files are gettext standard message files. I suggest you a thorough read of http://php.net/manual/en/book.gettext.php and other sources you can easily find googling about gettext.
