Files in explorer.exe are not sorted correctly

NTFSD

I am developping a FileSystem Driver and i have strange behavior when I
use
explorer on my driver. when I go in a directory of my filesystem, I get
the
file and directory that are sorted alphabetically and together :

I Have :
A1.txt
A2.txt
Dir1
Dir2
Dir3
Z1.txt
Z2.txt

instead of:
Dir1
Dir2
Dir3
A1.txt
A2.txt
Z1.txt
Z2.txt

when I implement IRP_MJ_DIRECTORY_CONTROL/FileBothDirectoryInformation

I return in FILE_BOTH_DIR_INFORMATION.FileAttributes
FILE_ATTRIBUTE_DIRECTORY when my item is a directory and
FILE_ATTRIBUTE_NORMAL for a file.
Explorer display my directory with good Icon and I can enter in, but
only
the sort is not working well.I have also tested with attribute set to
zero
or FILE_ATTRIBUTE_ARCHIVE instead of FILE_ATTRIBUTE_NORMAL but no
changes in
the behavior.

I create my device as a FILE_DEVICE_NETWORK_FILE_SYSTEM (this is the
same
with
FILE_DEVICE_DISK_FILE_SYSTEM) for avoid request for subfolder.

Have you any idea where I miss some informations to send from my driver
?
Thanks.

Check If you are passing the right information on IRP_MJ_QUERY_INFORMATION ioctl to your device.

I have checked this.
I return also the same attributes on
IRP_MJ_QUERY_INFORMATION/FileBasicInformation, but same behavior.
