Export attached files linked to a given view

Hi,

I've seen it's possible to retrieve all the files attached to a given database by converting the .ninox file into a .zip file.

However, I would like to export all the attached files of a given set of entries in a table (for instance, If I want to backup all my expense bills for a given month). Is there a way to do that ? Can I do that programatycally for a subtable in a form with an "export to .zip" button for instance ?

Thanks,

Lionel
