his is the traditional method and the method most of our users use. To locate the Languages folder, follow this path:

teta Theme :
wp-content/themes/teta/languages

Pinkmart Theme :
wp-content/themes/pinkmart/languages

Kite Plugins :
wp-content/plugins/kitestudio-core/languages
wp-content/plugins/kt-pro-tools/languages

Despite of being the most popular, this method has one downside. Whenever users update the theme and the plugin, the whole Theme folder and Plugin Folder are replaced with a new and updated folder, which in turn overwrites their translation files.

If you choose to store your language files using this method, remember that the file structure is only the language name. For example, if the language files are in the Deutsch language, the file names would be de_DE.mo and de_DE.po.

You can translate the default PO file with the POEdit tool. You can see here for more details.
