Hiding files and folders from the operating system

[andrewbb]

I've noticed a few products that hide folders and I'm curious how this
is implemented.

Can you hook into the shell api or possibly just hide it from Windows
Explorer?
Or do you have to write a file system driver?

Hidden folders and files use the hidden attribute. You can use a
FileInfo object or the static methods available in File to set it.

Try something like this:
System.IO.File.SetAttributes("foo.bar",
System.IO.FileAttributes.Hidden);
