A simple plugin that helps preserve your custom plugin translations through auto-updates by allowing you to put them in your WP languages folder.
Tired of your custom plugin and theme translation files getting wiped out every time you use the WordPress auto-updater? Install and activate this plugin and WordPress will look for missing translation files in the WP_LANG_DIR where you keep your WordPress translation files.
In WordPress 3.8 and greater this plugin's functionality is included in core. You can put translation files in: * Plugins: /wp-content/languages/plugins/textdomain-locale.mo * Themes: /wp-content/languages/themes/textdomain-locale.mo
