In my application i want to load a library from a new folder.
My application codeigniter.In my root folder there have `module` folder there have a library file i want to load that library in my model page.

This is my code:

```
$this->load->library('./modules/libraryname');  

```

When i loading library this code I got an error message.

```
Unable load the requested library

```

What is the mistake in my code.?
When i copy the library file to codeigniter's library folder and changing the code as :

```
 $this->load->library('libraryname'); 

```

Then it will load the library without error.

But i need to load this from only `module` folder.What i do?
