Optimise FindFiles.

Following is a recursive find files implementation. Does anyone have any ideas on how to further optimize it?

EDIT: No worries, I think this version is about as optimised as it is going to get.

Code:

---

static HRESULT FindFiles(LPTSTR szPath, BOOL bDeep, LPTSTR pAsterisk)
{
        /* FindFiles expects a modifiable string of MAX_PATH length
        * with trailing backslash and asterisk. eg. "C:\\my documents\\*" */

        HRESULT hr    = NOERROR;
        HANDLE hFind;
        WIN32_FIND_DATA fdata;

        hFind = FindFirstFile(szPath, &fdata);
        *pAsterisk = TEXT('\0');    /* Remove trailing asterisk */

        Gui_UpdateFindPath(szPath);

        if (INVALID_HANDLE_VALUE != hFind) {

                do {
                        if (pbj->bCancel) { hr = E_ABORT; break; }

                        if (!(fdata.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)) {
                                ProcessFile(szPath, &fdata);
                        }
                        else if (TEXT('.') != fdata.cFileName[0] && bDeep)
                        {
                                HRESULT hrSub;
                                TCHAR szChild[MAX_PATH];
                                LPTSTR szEnd;
                                SIZE_T cchRemaining;

                                if (SUCCEEDED(StringCchCopyEx(szChild, ARRAYSIZE(szChild), szPath,  &szEnd, &cchRemaining, 0)) &&
                                    SUCCEEDED(StringCchCopyEx(szEnd, cchRemaining, fdata.cFileName, &szEnd, &cchRemaining, 0)) && 
                                    SUCCEEDED(StringCchCopyEx(szEnd, cchRemaining, TEXT("\\*"),    &szEnd, NULL, 0)))
                                        hrSub = FindFiles(szChild, TRUE, szEnd - 1);
                                else
                                        hrSub = HRESULT_FROM_WIN32(ERROR_BUFFER_OVERFLOW);

                                if (FAILED(hrSub) && E_ABORT != hrSub)
                                        ReportError(MSG_ERR_FIND_SUB_DIR, hrSub, ET_WARNING2, __FILE__, __LINE__, szPath, fdata.cFileName);
                        }

                } while (FindNextFile(hFind, &fdata));

                FindClose(hFind);
        }
        else hr = HRESULT_FROM_WIN32(GetLastError());

        return hr;
}

Thanks.
