I have a minifilter, according to this reference link: https://docs.microsoft.com/en-us/windows-hardware/drivers/ifs/irp-mj-directory-control
we must get specifies one of the values described below:
FileBothDirectoryInformation
FileDirectoryInformation
FileFullDirectoryInformation
FileIdBothDirectoryInformation
FileIdFullDirectoryInformation
FileNamesInformation
FileObjectIdInformation
FileQuotaInformation
FileReparsePointInformation
But when i check below class always received 0
Data->Iopb->Parameters.DirectoryControl.QueryDirectory.FileInformationClass
also check other directory control and saw that for below class received FileFullDirectoryInformation (0n2)
and FileAlternateNameInformation (0n21) for delete and drag operation.
Data->Iopb->Parameters.DirectoryControl.QueryFileinformation->fileinformationclass
please guide me. How is this possible? Did i make a mistake?
