FTP Recursive File Upload, Download and Delete - c++

Question

I use wxFTP to make simple client and I'm stucked on how to Upload recursively my folder or do download (which would should be same as delete) from FTP server. I know how to upload single file, make FTP folder and delete file. I will appreciate an article (not necessarily in C/C++) that teaches the concept or if someone can help me here.
Code example will be appreciated but take that as secondary.
Sorry if it already asked and answered, I searched and didn't get anything that answered my question.

Answer 1

I translated the code in answer to this question to C++ and that was it.
Since So won't accept the answer and adds it to comments I have added Java code that I translated to C++. My current code is too long (in that it involves few functions and so not fit for SO I guess!
public void saveFilesToServer(String remoteDest, File localSrc) throws IOException {
FTPClient ftp = new FTPClient();
ftp.connect("ftp.foobar.com");
if (!FTPReply.isPositiveCompletion(ftp.getReplyCode())) {
ftp.disconnect();
log.fatal("FTP not disconnected");
}
ftp.login("foo", "qwerty");
log.info("Connected to server .");
log.info(ftp.getReplyString());
ftp.changeWorkingDirectory(remoteDest);
ftp.setFileType(FTPClient.BINARY_FILE_TYPE);
try {
upload(localSrc, ftp);
}
finally {
ftp.disconnect();
log.info("FTP disconnected");
}
}
public void upload(File src, FTPClient ftp) throws IOException {
if (src.isDirectory()) {
ftp.makeDirectory(src.getName());
ftp.changeWorkingDirectory(src.getName());
for (File file : src.listFiles()) {
upload(file, ftp);
}
ftp.changeToParentDirectory();
}
else {
InputStream srcStream = null;
try {
srcStream = src.toURI().toURL().openStream();
ftp.storeFile(src.getName(), srcStream);
}
finally {
IOUtils.closeQuietly(srcStream);
}
}
}
