FTP Sync Download Tree w/ Must-Match Constraints

See more FTP Examples

Demonstrates how synchronize a directory tree in the download direction, but only for files matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

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

        Ftp2 ftp = new Ftp2();

        ftp.setHostname("ftp.something.com");
        ftp.setUsername("my_login");
        ftp.setPassword("my_password");

        // Connect and login to the FTP server.
        try {
            ftp.connect();

            // Set the current remote directory to the root of
            // the tree to be downloaded.
            ftp.changeRemoteDir("/subDir1");
        } catch (ChilkatException e) {
            System.out.println(e.getLastErrorText());
            return;
        }

        // Possible synchronization modes 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.

        // This example will download all files, but only those files having filenames
        // that match *.gif and *.eml

        // Imagine our remote directory tree has these files and directories:

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

        // Indicate that we only want to create auto-create local directories (if needed)
        // for the files that are actually downloaded.  If SyncCreateAllLocalDirs remains
        // true, then the corresponding local directory is created for each remote directory
        // traversed regardless of whether files within are downloaded.
        ftp.setSyncCreateAllLocalDirs(false);

        ftp.setSyncMustMatch("*.eml; *.gif");
        int mode = 0;
        try {

            return;

        ftp.disconnect();

        // Show the files downloaded.
        StringTable st = new StringTable();
