    // The FakeMirrorDataMover class does the actual work of copying files from
    // the "cloud" to the "client" and updating the transfer status along the way.
    void CALLBACK FakeCloudProvider::OnFetchData(
        _In_ CONST CF_CALLBACK_INFO* callbackInfo,
        _In_ CONST CF_CALLBACK_PARAMETERS* callbackParameters)
    {
        //FileCopierWithProgress::CopyFromServerToClient(callbackInfo, callbackParameters, ProviderFolderLocations::GetServerFolder());
    
            const UINT CHUNKSIZE = 48 * 1024 * 1024;
            UINT len;
            LONG64 offset = callbackParameters->FetchData.RequiredFileOffset.QuadPart;
            LONG64 requiredLength = …
