Multiple instances of a mini filter on single volume

NTFSD

Hi All,

I have a mini-filter that is used for dual purposes.
a. File blocking
b. Encryption/Decryption

I want to achieve these 2 functionalities at different altitudes. Fileblocking being at the “FSFilter Top” load order group and Encryption “FSFilter Encryption” load order group.

I wanted to know if there is a function such that I can query the instantiation of the filter on a volume at a unique altitude and based on that decide the functionality supported.

thanks,
Nikhil
