To edit a .mo file you first need to have the .po version of it.
Then you can edit it with POEDIT
If you don’t have any of those things, first get POEDIT
http://www.poedit.net/download.php
If you only have a .mo file and not the .po but wish to add/edit the translations, you can “decompile” or reverse the .mo file into a .po file from the command line with poedit , ie.
START -> RUN
/program files/poedit/bin/msgunfmt ab_AB.mo > ab_AB.po
Thank you, so much !
I’m updating the italian version of the language file,
i found several mistakes and missing translations in that file.
Would you like to have a copy of file with the right words ?
The svn looks badly out of date for Italian
