Hi
In my filter driver I need to get the pointer to the Bitmap of cluster
allocation by file systems. One way is to get it by using
FSCTL_GET_VOLUME_BITMAP but for a large volume it will eat up a lot of space
to keep the volume bitmap which will be in Non Paged Memory which I don’t
want to use. Is there any way to get the pointer to the Used Clusters Bitmap
that file system keeps?
Thanks in advance.
