Upload file to wordpress folder before send email

I am trying to save uploaded files before sending the email.

Basically the same as this question (https://www.ads-software.com/support/topic/plugin-contact-form-7-upload-file-to-wordpress-folder-before-send-email?replies=9) from 4 years ago.

However the answer given no longer seems to work.

I am trying to do this in the wpcf7_before_send_mail hook:

$cf7->uploaded_files no longer works

And with something like this: $_FILES[‘file-869’] , I can see the file temp name but it has already been deleted from the /var/tmp folder before I can grab it and move it somewhere else.

Does anyone know how to do this?

Thanks,
Scott
