You can use your favorite FTP software or file managers available in your hosting control panel to navigate to <Joomla! root folder>/components/com_cmlivedeal/language/ folder. In this folder you can see the folder en-GB, this is where the language files of English are stored.

In this language folder, you create a new folder for your new language, the name of the folder is the language tag. Follow the above example, you create a new folder fr-FR.

Go to en-GB folder, copy\_cmlivedeal.ini file in this folder to the new language folder that you just create (fr-FR as in the example).

In the new language folder folder, rename\_cmlivedeal.ini to\_cmlivedeal.ini, xx-YY is the language tag of your new language, eg fr-FR.
