In summary, I finded way to use the GetOpenFileName for select folder (not files).
I repeat a posts of this forum, may be. But I think, this topic, will be more complete.

OpenFileDialogg proc hwnd:DWORD
   
    PUSH SIZEOF OPFILESTR
    PUSH OFFSET OPFILESTR
CALL RtlZeroMemory@8

PUSH SIZEOF szFile
        PUSH OFFSET szFile
CALL RtlZeroMemory@8

LEA EAX, [szFile]
MOV BYTE PTR [EAX], '*'
   
    MOV OPFILESTR.lStructSize,SIZEOF OPFILESTR
    MOV EAX, hwnd
    MOV OPFILESTR.hwndOwner, EAX
    MOV EAX, OFFSET szFile
    MOV OPFILESTR.lpstrFile, EAX
    MOV OPFILESTR.nMaxFile, SIZEOF szFile
    MOV EAX, OFFSET strFilter
    MOV OPFILESTR.lpstrFilter, EAX
    MOV OPFILESTR.nFilterIndex,1
    MOV OPFILESTR.lpstrFileTitle,0
    MOV OPFILESTR.nMaxFileTitle,0
    MOV OPFILESTR.lpstrInitialDir,0
    MOV OPFILESTR.Flags, OFN_NOVALIDATE
   
    PUSH OFFSET OPFILESTR
        CALL GetOpenFileNameA@4
       
   
    ret 4
OpenFileDialogg endp

no need to zero the entire szFile buffer

    mov word ptr szFile,'*'
sets it to '*',0

also, if you have cleared out the OPENFILENAME structure, no need for...

Code Select Expand

    MOV OPFILESTR.lpstrFileTitle,0
    MOV OPFILESTR.nMaxFileTitle,0
    MOV OPFILESTR.lpstrInitialDir,0
