Hi, which viewer version on which OS are you using? (2.x uses another file transfer protocol...)

I register the TightVNCFileTransfer extension on the client and server, and then test in the client to let the server create a folder。HandleRFBServerMessage often returns false, and then the client disconnect。 The same is true for my test transfer file. I wrote the code in Arch Linux. libvncserver-LibVNCServer-0.9.14 library is used.The remote image and remote control are all normal, only the file transfer will have problems.

rfbRegisterTightVNCFileTransferExtension();

void FileTransfer::createRemoteDirectory(const QString &dir)
{
    rfbFileTransferMsg ft;
    ft.type = rfbFileTransfer;
    ft.contentType = rfbCommand;
    ft.contentParam = rfbCDirCreate;
    ft.size = 0;
    ft.length = Swap32IfLE(dir.length());

    WriteToRFBServer(m_client->getClient(), (char *)&ft, sz_rfbFileTransferMsg);
    WriteToRFBServer(m_client->getClient(), (char *)dir.toLocal8Bit().data(), dir.length());
}

may I ask if there is an example of using TightVNCFileTransfer in libvncserverclient?

@zzxyb please see https://github.com/LibVNC/libvncserver/blob/master/examples/server/filetransfer.c and especially note the leading comment. No client example AFAIK.
