Easy! 🙂 Go to your Private Messages, and click on Private Files. Upload the file, set a password (to keep it secure!) then “Share” it to the buyer’s username provided on the order notification 🙂 They’ll receive the password automatically. You can also send a buyer a folder of multiple downloads by creating the folder, setting a folder password, then uploading the files–edit their status to “Public”, then save them to the password protected folder, and viola. You can then “Share” the folder with your buyer 🙂 Please mind the 2GB file limit per video!
