Quoting John Fletcher net@twoedged.org:
Hi everyone,
I'd like to set up multiple sites using subfolders. Basically the client wants their site in multiple languages, but doesn't want to attempt to synchronise the various sites and pages between the languages or do anything that the content translation/i18n modules offer.
So I want a bunch of independent sites in a multi-site setup. This could easily be achieved using domains like www.example.com, de.example.com, fr.example.com etc.
Possible
The question is, can I do the same thing putting the sites at: www.example.com, www.example.com/de, www.example.com/fr.
Possible
Have a look at the examples in the comments of the settings.php file.
This guy explains the same problem quite well http://drupal.org/node/30857, but then the rest of the thread seems to lose track of the task and not give a decent answer.
The first comment of that issue explains what to do.
Make a directory sites/www.example.com.fr, another sites/www.example.com.en and another sites/www.example.com.de. Then copy the pristine version of the settings.php file from the sites/default folder to each of these or if you're using version 6 you copy the default.settings.php.
(it might be easier to understand the question if you forget about i18n altogether and just consider the question of putting multiple sites in subfolders).
The question becomes what data should be shared? Or are they independent? If each site shares the same database be sure to set a db_prefix for each site (something like fr_ or de_).
