Translate interface (export/import) I have two languages: 


french
arabic


I want to completely translate the arabic interface. If there a way to export the englisch translations, add the arabic one and reimport the file?
It can be done using Translation template extractor module


  If you are a translator, install the module on a Drupal site as you would with any other module. Once potx module is turned on, you can go to the "Extract strings" tab on the Locale administration interface, select the module or theme you want to have a translation template for, and submit the form. You will get one single template file generated.
