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

CkoSFtp *sftp = [[CkoSFtp alloc] init];

BOOL success = [sftp Connect: @"my-ssh-server.com" port: [NSNumber numberWithInt: 22]];
if (success == YES) {
    success = [sftp AuthenticatePw: @"mySshLogin" password: @"mySshPassword"];

// Synchronize the remote directory tree rooted at "syncDownloadTest/xml"
// with the local directory tree rooted at "qa_output"
// Both directories are relative paths.  The remote directory
// is relative to the HOME directory of the SSH user account.
// The local directory is relative to the current working directory of the process.
// It is also possible to use absolute paths.

NSString *remoteDir = @"syncDownloadTest";
NSString *localDir = @"qa_output";

// Possible modes that can be passed to the SyncTreeDownload method are:
// mode=0: Download all files
// mode=1: Download all files that do not exist on the local filesystem.
// mode=2: Download newer or non-existant files.
// mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server.
// mode=5: Download only missing files or files with size differences.
// mode=6: Same as mode 5, but also download newer files.
// mode=99: Do not download files, but instead delete remote files that do not exist locally.

// This example will use mode 6 to download missing, newer, or files with size differences.
int mode = 6;
// This example will turn on recursion to synchronize the entire tree. 
// Recursion can be turned off to synchronize the files of a single directory.
BOOL recursive = YES;
success = [sftp SyncTreeDownload: remoteDir localRoot: localDir mode: [NSNumber numberWithInt: mode] recurse: recursive];
if (success != YES) {
    NSLog(@"%@",sftp.LastErrorText);
    return;
}

// Examine the list of downloaded files.
// The downloaded files are listed one per line in the SyncedFiles property.
// Local directories that were created will be listed with a trailing "/" char.
NSString *fileList = sftp.SyncedFiles;
NSLog(@"%@",fileList);
NSLog(@"%@",@"");

// For example:

// data/
// chiliPepper.gif
// helloWorld.pdf
// alice.key
// anter_cert.pem
// text/
// accentedLatin1.txt
// accentedUtf8.txt
// abc/
// abc/chiliPepper.gif
// abc/ghk/
// text/something/
// text/PolishEmailBody.txt
// text/frenchUtf8.txt
// text/helloWorld.txt
// data/chiliPepper.gif
// data/xyz/
// data/xyz/dkimHtmlBody.txt
// data/xyz/emailForCreateDsn.eml
// data/xyz/dkimVerifyTest.eml

// You could load the strings into a Chilkat string table..
CkoStringBuilder *sb = [[CkoStringBuilder alloc] init];

// Find out how many files + dirs

int i = 0;
while (i < [st.Count intValue]) {
    NSLog(@"%@",[st StringAt: [NSNumber numberWithInt: i]]);
    i = i + 1;
