Hi Frenske,
look at this what i attach in this post - it can help you
it's the dutch (nl.po) from openatv, and in this file you can find the complete translations to filecommander plugin, because openatv translated their plugins in the
general locale for e2 (in the nl.po in this case)
nl.po.zip 180.17KB 5 downloads
you can search in this file for the original filecommander to translate code with notepad++ and compare it with your .po in poedit
regards
Pike
