Doubt in Filter Driver!

Hi All,

Ilamparithi here.

I need to develope a filter driver in 2000.

At the driver level, i need to know which files are opened, read, written and closed.

While i try to do this, Iam not able to get the full file name.

I mean, iam getting the file name without the Drive Name.

Eg.

If the file opened is C:\New\xx.txt, Iam getting the file name as \New\xx.txt.

Iam getting this info from File_Object's filename.

Also, for a mapped drive iam getting the drive name properly!

How to get the drive name correctly for other drives?

With Regards,
A.Ilamparithi.
