Locale Bulk

This module allows you to import and export translations (.po) files in a bulk mode.

Drupal by default allows users to import and export translations individually (one language -> one group of translations).
If you manage a multilingual site with different groups of the translation process can be long and tedious. With this module, the import and export, including the use of drush, is fast and suitable.

Requirements

• Drupal 7.x
• Locale module
• PHP >= 5.2

How to use it

• Download and enable the module
• Go to admin/config/regional/translate/locale-bulk

You can also use drush to import translations, for help execute:
drush help lbulk

How it works

With one click you can download an archive that contains po files for every translation group (default-interface, taxonomy, block etc) and then you can upload it to import strings.
You can also import translation from a directory.

This module works with a name convection: every file has a structure en_taxonomy, where "en" is the language code and "taxonomy" is the name of a translation group. Only files that respect this convention will be imported.

It adds also a drush command to import translations from a directory.
