How to associate a taxonomy term to an uploaded file with PUPLOAD module

Hi,

How to associate a taxonomy term to an uploaded file with drupal 7 ? For example I add a node with a file type field, and upload a file then i try to associate a taxonomy term to the uploaded file.

For example :

I have a node Document with 2 file uploaded like this : Document : File1, File2 and i have a taxonomy Structure when i create a document i upload the two files and associate them with two different Structure for example : Document : File1-Structure1 and File2-Structure2. I am using the pupload module.

Thanks
