How to know all file systems and mounted volumes loaded?

NTFSD

Hi,

Is there a way to know all file systems and mounted volumes loaded? Without loading at boot time to avoid a system restart when the file system filter is installed.

Thanks.

Ratmil -

Apparently IoRegisterFsRegistrationChange will notify
you immediately of all currently loaded file systems,
even if you call it after they actually loaded. The
technique used in sfilter is to call
IoEnumerateDeviceObjectList for each file system
driver (to find the mounted volumes) from within the
FsRegistrationChange callback routine.

It only has this behavior on XP and later. On XP and
later it also does not enumerate RAW devices.

I searched the internet for this funcion (IoEnumerateDeviceObjectList), I
only found one page.
I guess it is only for XP.

How to enumerate all mounted devices.
I was doing loop starting from “DriverObject->DeviceObject” and then moving
through “NextDeviceObject” but I was attaching some devices I don’t want,
like LanmanDatagramReceiver. How could I enumerate only mounted devices?
Thanks.
