Of Filesystems And Other Demons: What's New in Win8 for File System Filters

Of Filesystems And Other Demons: What's New in Win8 for File System Filters:

"One thing that's been missing from FltMgr since the beginning and the developers have complained about was the ability to filter other devices that have file system semantics, and in particular named pipes (NPFS). It looks like in Win8 that's finally going to happen and we'll finally be able to write minifilters for NPFS. Moreover, it looks like the folks in Redmond went the extra mile and have added support for the Mailslot file system (MSFS) as well:

C:\Windows\system32>fltmc volumes                                                            
Dos Name                        Volume Name                              FileSystem   Status 
------------------------------  ---------------------------------------  ----------  --------
                                \Device\Mup                              Remote              
C:                              \Device\HarddiskVolume2                  NTFS                
                                \Device\HarddiskVolume1                  NTFS                
                                \Device\NamedPipe                        NamedPipe           
                                \Device\Mailslot                         Mailslot            
D:                              \Device\CdRom0                           UDFS        Detached
                                \Device\HarddiskVolumeShadowCopy1        NTFS                
D:                              \Device\CdRom0                           UDFS                

There is even an in-box filter attached to NPFS:
