Hiding the physical path of a file in downloading

[Majid Shahabfar]

I want to let some users download some files from my website and I don't want them to see the physical path of the downloading file. I moved the files in a folder outside of my web folder and use Response.WriteFile(filePath) to download them. this help me to hide the path but this method doesn't support resume download which I really want it. So what method you recommend I use? Thanks
