Uploading Videos as a contributor to Adobe Stock

I'm looking to upload my videos to Adobe Stock as a contributor but am having a hard time locating where the file goes once I upload it to FTP Filezilla as recommended by Adobe on their stock upload page. When I uploaded them to the FTP, files disappear from the FTP and I was unable to locate them in Filezilla or on the Adobe Stock pages of my account. How do I verify that these files have been uploaded in my account? Thank you!
