    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    ftp := chilkat.NewFtp2()

    ftp.SetHostname("ftp.example.com")
    ftp.SetUsername("login")
    ftp.SetPassword("password")

    // Connect and login to the FTP server.
    success := ftp.Connect()
    if success != true {
        fmt.Println(ftp.LastErrorText())
        ftp.DisposeFtp2()
        return
    }

    // Change to the remote directory where the file will be uploaded.
    success = ftp.ChangeRemoteDir("temp")
    if success != true {
        fmt.Println(ftp.LastErrorText())
        ftp.DisposeFtp2()
        return
    }

    // In this example, assume that a previous FTP upload failed,
    // and the incomplete file (bigFile.zip) exists on the FTP server.
    // You only need to set the RestartNext property to resume
    // the upload.  When RestartNext is set, the next call
    // to PutFile (or PutFileFromBinaryData, PutFileFromTextData)
    // will automatically resume the upload from the point of failure.
    // (The way it works is that the FTP component sends a "SIZE"
    // command to the FTP server to find out how many bytes of
    // the file already exist on the server.  It then begins
    // uploading from that point.

    // Note: After PutFile is called, the RestartNext property
    // is automatically set to false.
    ftp.SetRestartNext(true)

    // Upload a file with restart.
    localFilename := "bigFile.zip"
    remoteFilename := "bigFile.zip"

    success = ftp.PutFile(localFilename,remoteFilename)
    if success != true {
        fmt.Println(ftp.LastErrorText())
        ftp.DisposeFtp2()
        return
    }

    success = ftp.Disconnect()

    fmt.Println("File Uploaded!")

    ftp.DisposeFtp2()
