Adult Pay Per Download Website Movie Data Base

I’m creating an adult website for someone and its a pay per download site, however what is the best way to map the videos or get them in the data base without uploading them individual, they are 1.6 GB to 2.5GB in size for the most part. There’s over 1.5TB of movies and there on the server already in a folder. When i try to add them as a file in the product it takes the time to re-upload it, which takes forever or times out. I cant be doing that. Is there a faster way to map these in the products? :confused:
