To check if a folder is a special shell folder in Win32API code, you can use the IShellFolder interface's ParseDisplayName function. Here's an example:n`nSTDMETHODIMP CMyFolder::ParseDisplayName(IPersistFile* pPersistFile, LPOLESTR *ppnameOut, IMONIKER **ppMk, IBindCtx **ppbc)n{nIUnknown *pUnk = nullptr;nIShellFolder *pShellFolder = nullptr;nHRESULT hr = S_OK;nnhr = pPersistFile->Load(ppnameOut, STGM_READ | STGM_DELAYED_WRITE);nif (SUCCEEDED(hr)) {nhr = CoCreateInstance(CLSID_ShellFolder, NULL, CLSCTX_INPROC_SERVER, IID_PPV_ARGS(&pUnk));nif (SUCCEEDED(hr)) {nIShellDispatch *pShellDispatch;nh = pUnk->QueryInterface(IID_PPV_ARGS(&pShellDispatch));nif (SUCCEEDED(hr)) {nIFolder *pFolder;nhr = pShellDispatch->GetParent((OLECHAR**)&ppnameOut, &pFolder);nif (SUCCEEDED(hr)) {nhr = pFolder->QueryInterface(IID_IShellFolder, (void **)&pShellFolder);npFolder.Release();n}n}n}n}nIFolder *pSpecialFolder;nh = pShellFolder->ParseDisplayName(pbc, NULL, ppnameOut, &pSpecialFolder);nIFCObject::Release(pUnk);nIFCObject::Release(pShellFolder);npSpecialFolder.Release();nrtruntime_assert(SUCCEEDED(hr));nreturn hr;n};n`
