Explorer and encryption

Hi all,
Does anyone know off-hand by what method the explorer app is
able to determine which files/directories are using EFS so that it can
color their names in the explorer window? Just wondering what you would
see at a FSFD level coming down the stack.

From DDK:

#define FILE_ATTRIBUTE_ENCRYPTED 0x00004000

Probably just GetFileAttributes/Ex, and testing for
FILE_ATTRIBUTE_ENCRYPTED.
