Making my UDF reader get first preference

NTFSD
1

Hi Everybody,

I am facing a problem in my FSR(File system Recognizer)
for my UDF reader(myFSD).
In WinXp after i load my FSR in Start type (0x1 i.e. Boot time) and myFSD(start type 0x3 i.e manual) and get a
request to mount basically a volume in CD/DVD written
in UDF standard format , if default Win XP UDF reader
is there it reads it and my FSD is never loaded because
request doesnot come to my FSR.

Can you tell me is there a way or what is the sequence
of getting the request for WinXp in terms of Recognizers??
I have found out that fs_rec(Key in the Registry) contains the default windows filesystem entries.

Please can anybody help me in clearing these doubts??

  1. What is the sequence of getting the request if we have
    more than one FSR to recognize the same type of volume
    I mean suppose Default UDF-FSR is there and MY-FSR is
    also there for recognizing standard UDF formatted media(CD/DVD) then which FSR(File System Recognizer) will
    get the request FIRST???

Thanking you in advance and patiently waiting for a helping Thought??

Have a nice day/Night!

Mounting is done in order of priority: first normal priority, then low
priority. Within a priority class, the file system is called in reverse
order of registration (Last Registered, First Called).

If you want to be called to mount BEFORE UDFS you must register AFTER UDFS.
You could do this by filtering fs_rec and watching for the
IRP_MJ_FILE_SYSTEM_CONTROL/IRP_MN_LOAD_FILE_SYSTEM request for
Udfs_Recognizer. When that returns STATUS_SUCCESS (in completion) then you
can load your own file system driver. Since UDFS is already loaded, you can
now load your driver and it will be LAST registered and FIRST called.
