Hi sharkrc - welcome to PCHF! Sorry it has taken us so long to respond to your question. We're all in different timezones and very busy so sometimes it can take a while to get an answer.
I would recommend using Hamachi for this - it will create a secure link between your home and work pc and will enable you to access the files on your home pc. Hamachi is free for small business and personal use.
As long as Hamachi is running on your home PC you will always be able to connect to it from work or any other computer with Hamachi installed as long as you know the Hamachi IP and password.
