Answer 1

Try This:

$config['file_name'] = "yourCustomFileName";

Answer 2

If your $config is with this code: $config['encrypt_name'] = TRUE; the name of your file will be forced to rename with a encrypt name, just remove the code.

Answer 3

when you use do_upload() function its rename file name if already exists and upload file

System->libraries->Upload.php

default function of do_upload() return true or false replace

return $this->upload_path.$this->file_name;

and in another file

 <input type='file' name='userfile'/>


<?php
    $upload_file_name = $this->upload->do_upload('userfile');
                $finalname;
                if (!$upload_file_name) {
                    $finalname = 'default.png';
                } else {

                    $split_data_upload_file_name = explode("/", $upload_file_name);
                    foreach ($split_data_upload_file_name as $i => $value) {

                        $finalname = $value;
                    }
                }
