Sync a Single FTP Directory Down to Local

See more FTP Examples

Demonstrates the Chilkat Ftp2.SyncLocalDir method, which synchronizes files from the current remote directory into a local directory without descending into subdirectories. The first argument is the local root and the second is the download mode.

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

    //  the local root and the 2nd is the download mode.

    ftp.hostname = "ftp.example.com"

    //  Normally you would not hard-code the password in source.  You should instead obtain it
    //  from an interactive prompt, environment variable, or a secrets vault.
    ftp.password = "myPassword"

    //  This is the single-directory (non-recursive) form of SyncLocalTree; it uses the same modes.
    //    0 = all selected files
    //    1 = files missing locally
    //    2 = missing locally, or newer on the server
    //    3 = only files that exist locally and are newer on the server
    //    5 = missing locally, or a different size
    //    6 = missing, different size, or newer on the server
    //   99 = do not download; delete local... (see docs)
