Translating Directory plugin

Hello,

I was looking to translate some text strings for the Directory plugin. I looked around for a PO file and found it in this location: http://screencast.com/t/cixhxEjzs

I opened it in Poedit and saved, I also saved the en_EN.po to fr_FR.po and replaced the files there, however the translation I made did not show up.

What am I doing wrong here?

Thank you.
