Problem controller within subfolder

[eluser]Aircraft42h[/eluser]
Hi,

Firstable I had all files in my subfolder admin, and it worked very well.
But I would like to explode with other folders :

Like that :
controlers
admin
user
content
customer

I still have a file in admin and it's ok but i can't access file inside user, content or customer, I have always 404 page not found.

any ideas ?
I m' very tired, more than 3 hours to search what's wrong
