Re: How to add and modify .mo file
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
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
