Here are the steps to securely transfer files and documents to others:

1. Use a cloud-based file sharing service such as Dropbox, Google Drive, or OneDrive


2. Encrypt the documents with a strong password


3. Share the documents with a secure link instead of attaching them to an email


4. If you are sending the file to someone who does not have the appropriate software to open it, consider using a free file converter service such as Zamzar.


5. Make sure to delete the file once it has been sent and received.
