Create path longer than MAX_PATH

Why this does not work ?

Code:

format pe gui 4.0
entry start
include 'win32wx.inc'
overmaxpathname   fix 'xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_',\
                      'xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_',\
                      'xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_',\
                      'xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_',\
                      'xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_xxxxxxxxx_',\
                      'xxxxxxxxx_.txt'        ; 264 bytes name



section '.data' data readable writeable

   filename         TCHAR  '\\?\d:\',overmaxpathname,0


section '.code' code readable executable
start:
        invoke  CreateFile, filename, GENERIC_READ or GENERIC_WRITE,\
                FILE_SHARE_READ or  FILE_SHARE_WRITE, NULL, CREATE_ALWAYS,\
                FILE_ATTRIBUTE_ARCHIVE, NULL

        .if eax = INVALID_HANDLE_VALUE
                invoke MessageBox, 0, 'NIEPOWODZENIE',0,0
                jmp    endstart
        .endif

        mov     ebx, eax
        invoke  MessageBox,0,'successik','utworzono plik',0
        invoke  CloseHandle, ebx
     endstart:
        invoke  ExitProcess,0






section '.idata' import data readable
library kernel32,'kernel32.dll',user32,'user32.dll'
include 'api\kernel32.inc'
include 'api\user32.inc'

ofcorse when i change 'overmaxpathname' to name less than MAX_PATH everythink is ok.
Forgive my english.
