Desmoric had done a translation, and is providing a po file and a mo file. Theses are available here:Re: PCLinuxOS Live USB Creator à traduire
I suppose they should need to be tested, and I am not sure how to do that ? In my system I actually have theses 2 files:
$ find . -name "*usb*"
and I am not sure what they do, as there has been no translation for French up to now (and "rpm -qf <argument>" declares they don't belong to any package, although pclos live usb creator is installed).
