In my filter driver when I get the name of the file associated with a FileObject , I am not getting the driver letter. Instead i am getting something like below.
\device\Harddiskvolume2\MyFile.txt
I am using “ObQuerynameString” to get the name .
Actually I wanted the name to be D:\MyFile.txt
Does any one experience this kind of problem? Any suggestions please?

Look at FilesSpy example in DDK use SpyGetFullPathName function . Take
care to set the lookupFlags.
SetFlag( lookupFlags, NLFL_IN_CREATE );
Hope it helps.

This is not a problem, this is by design.
In the layer of FS drivers and filters, (in fact, in the layer
of native API), there are no drive letters.
There are volume names. More drive letters
could be assigned to one volume, but a volume
must not have a drive letter at all.
You may use RtlVolumeNameToDosDevice,
but above rules apply to it as well.
L.
In addition to the other suggestion, you must be able to handle the case
where there is no drive letter. I routinely configure my system so that
I have only one drive letter, with other volumes connected via mount
points. If your filter can’t handle that configuration, it will likely
break in production environments.
