To download large files from server, I have changed the below settings in php.ini file:
Upload_max_filesize - 1500 M
Max_input_time - 1000
Memory_limit - 640M
Max_execution_time - 1800
Post_max_size - 2000 M
Now, I am able to upload and download 175MB video on server. Since, I have the dedicated server. So, making these changes were easy.
