Pretty sure. If you look at Windows' native version of stat, it will return you st_ino = 0. Or maybe you where referring to something else, and I just missed your point?

AFAIK, the ino in the index is only to be _really_ sure that nothing has changed with the file, and we can just skip it on Windows. If in doubt, try running this on your Windows box:

#include <windows.h> #include <stdio.h> #include <sys/types.h> #include <sys/stat.h>

int main(int, char **)
{
    wchar_t DirSpec[] = L".\\*";
    WIN32_FIND_DATA FindFileData;
    HANDLE hFind = FindFirstFile(DirSpec, &FindFileData);
    if (hFind == INVALID_HANDLE_VALUE) {
        printf ("Crap happened: %u\n", GetLastError());
        return -1;
    }

    struct _stat buf;
    while (FindNextFile(hFind, &FindFileData) != 0) 
    {
        if (!_wstat(FindFileData.cFileName, &buf))
            printf("file: %S, ino: %u\n", FindFileData.cFileName, buf.st_ino);
    }

    FindClose(hFind);
    return 0;
}
