How to upload file ?

[eluser]mahe11[/eluser]
I check my mimes.php file and mime types

Code:

'xls'    =>    array('application/excel', 'application/vnd.ms-excel', 'application/msexcel'),
'ppt'    =>    array('application/powerpoint', 'application/vnd.ms-powerpoint'),
'doc'    =>    'application/msword',
'rtx'    =>    'text/richtext',
'rtf'    =>    'text/rtf',

are present for specified file types.

really Thanks to all @Atharva. I post new topic for that
