Secure Time-Limited File Transfer

I have a bundle of Adobe Illustrator (AI) design files that need to be transferred to a printer via a hard drive. Here are more details:

- The files must be automatically permanently deleted exactly 1 hour after being printed.
- I am open to solutions involving ethical hacking if necessary.

Ideally, you should have:

- Profound knowledge and experience in secure file transfer
- Experience or knowledge in ethical hacking
- A demonstrated ability to handle AI files sensibly
- A keen understanding of timing mechanisms for file deletion

Please, only apply if you can guarantee a secure and efficient execution of the task within the stated conditions.
