WordPress MU

in plugins folder if u can add a folder containing files and all files will be activate if u activate the plugin
but in mu-plugins folder if u add a folder containing files .. non of the files will be activate except if the file that contain the activation code moved to mu-plugin folder

can coders edit that .. as this will help alot in make most of plugins made for wp cab be easly integrated to WpMu

Most people are just sticking a file in mu-plugins to include the sub-folder. If you really want to see it included (or at least get an official opinion, file a ticket. :)

Personally, I wouldn't want it to dig through sub-directories. Calling a file in a sub-directory is overall much more friendly than having it include every single file, in every single directory.

You do know that "most" plugins work just fine in the actual plugins directory, right? As well as understand what the additional mu-plugins directory is for? (It's for files that MUST be loaded on every single page, for every single blog.)

99% of plugins don't need to be in mu-plugins, really.

is there a code that make me include a specific files in sub-directories

Uh yeah. include, include_once, require, require_once...
