How can I remove sub-folder(controller) name from URL

[eluser]veledrom[/eluser]
Hi,

I have many sub folders under controller folder. When I call a class under any of those sub folders, I see sub folder name attached to the URL. I want to remove folder name from URL but how do I do it?

EXAMPLE:

Folder structure: application/controller/<b>mysubfolder</b>

URL: localhost/index.php/<b>mysubfolder</b>/class/method

How can I remove <b>mysubfolder</b> wording? I have many folders so It has to be dynamic solution.

Thanks in advance
