Hollo All:

I had writed a File System Filter Driver based on hooking one specific
logic volume device. I want to redirect for reading from and writting to
some files within one same that logic volume device has been hooked.
Example: I had hooked a logic volume device : "D:\"
When application or user program read or write these files in
volume hooked "D:\1.dat", then I want to return data from Read option by
other file in different location---- "E:\1.dat". So I handle a lot of IRP
request and some FastIoDispach, but when application opened this file, it
always appears a message box that means --- "Not enough memory available to
complete this operation. Quit one or more applications to increase available
memory, and then try again." And returns nothing data.

Now I dont understand this reason cause this notice event. Maybe some IRP
and FastIoDispach request handles is incorrect or others request was not
handled.

Please help me.


Best Regards.

Vic

If I understand what you are trying to do, there is a feature in Windows
called Mount Points to do this.
