Add files by URL?

[tomwin]

Hope someone can help me understand this?

When i add a file by URL, will it upload, save it to my server?

If i upload let say 2 file by URL to a package i can see whole URL when i start download the file. But when i upload just one file by URL to the source URL is hide. But the problem if i start to charge for the file and i upload the file to a package and someone buy to download the file he or she can see the source from where the file is from. And the buyer can then use the source URL to give to a friend for free.

If i use a file hosting like google drive or some other file hosting company they will see the source URL.
