Can I use another server/disk to store files using FileTable concept?

Hi All, I tried samples of FileTable in SQL Server 2012 to store files in database. I have following questions.

1. When I right click on FileTable, and say Explore File Table Directory, I was taken to a directory. But if I search the same directory in my server/machine, the directory is not available. Please explain the logic behind it?

2. Can I use some external server/disk as a directory for FileTable?

3. How easy is to use FileTables using .Net web applications?

Thanks
