// 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.
