I have two methods with which you can send me files:
The simplest is ShareFile, which I buy from Citrix. I list the link at the bottom of each of my emails. When I send you files via ShareFile, the files go through a secure “tunnel” from my computer to ShareFile; then you click on the link I send you to get the files from ShareFile to your computer.
This also works the other way: you can use the link to upload files securely.
Here is the Sharefile link: https://thomashealycpa.sharefile.com/r/r36fae4db4ff4e6f9
