How can I upload autocad files (.dwg,.dxf,.dwf etc) .

I added following lines

Code:

'dwf' => array('drawing/x-dwf', 'model/vnd.dwf'),
'dwg' => array('application/acad', 'image/vnd.dwg', 'image/x-dwg'),
'dxf' => array('application/dxf', 'image/vnd.dwg', 'image/x-dwg')

in

Code:

/system/application/config/mimes.php

file and tried to upload .dwg file. It showed an error like this: The filetype you are attempting to upload is not allowed. How can i then upload a .dwg file?

i am using this following code to upload any type of file from the controller after defining in the mimes.php
use * in allowed types
$filedata = array(
'allowed_types' => '*',
'upload_path' => $this->folder_path,
'max_size' => 20000
);

i need to allow the users to upload autocad files only.

Those mime types simply didn't work for me. I used "application/octet-stream" and tried, it worked !

Use allowed types in config.php.
