Usually a language consists of at least a linguistic identifier and a regional identifier (for instance: English + United States will be “en-US”). Files are mapped to languages in the File Manager. For instance when you add a language WebTranslateIt automatically creates target files for each master file in the File Manager. Also, when you add a new master file in WebTranslateIt, target files are automatically created and mapped to existing languages.Starting Price: $58 per month -
