Attaching source

Hi all,
is some difference between \Device\Harddisk0\Partition1 and ??\c: ???
When I’m writing file system filter, to what I must attach?
I want implement very simple encoding mechanism.
And can I attach to a file? (Something like ??\C:\temp\disk.img)

One is a symlink to another.

To any - the device object will be the same.

Harddisk0\Partition1 is not necessarily C:.
I know it is not ideal behavior, but there are some 3rd-party disk
class drivers (for specific model disks) that are installed to start
before DISK.SYS. This means that Harddisk0\Partition1 will be created
by the other driver, while C: will refer to a DEVICE_OBJECT created by
DISK named HarddiskN\Partition1, where N > 0.
