How do you use wp_handle_upload
function and apply_filters
together to upload files on a specific path? What is going to be the override?
For example:
$overrides = array('file' => 'C:\uploads\filename.pdf','message' => 'File written');
apply_filter('wp_handle_upload',$overrides);
or something like that? Or is this the right code?
The real question in here is: what $overrides
can be used as the key to this associative array?

You could make it easy by just getting the allowed mime types like:
If you look at the codex for Default allowed mime types, you could manually specify which ever mime types you want in that format.
An example would be like this answer.
