Hi All,

I have written a file system minifilter driver, I am getting files name begining with device name eg. HardDiskvolume1\Amit\Temp.txt but I want the name as c:\Amit\Temp.txt. Please tell me how I do it?

Thanks & Regards,
Amit.

you could use FilterGetDosName but that would require you to read the
docs… :slight_smile:

Seriously, how you tackle the problem depends on what your doing. My
latest creation, the filter creates a log with a bunch
of device names + paths… When the usermode app processes the log - it
calls QueryDosDevice
building a table of device names and then using regular string functions
it produces the desired output.

Your question kinda depends on what your wanting too do. If your wanting
to process the file in usermode, instead pass up
the volume guid with the path appended. All Usermode functions will
accept this name (with the exception of SFC api’s).
