Synchronize Remote Directory Tree

See more FTP Examples

Uploads a directory tree from the local filesystem to the FTP server. Synchronization modes include:

mode=0: Upload all files
mode=1: Upload all files that do not exist on the FTP server.
mode=2: Upload newer or non-existant files.
mode=3: Upload only newer files. If a file does not already exist on the FTP server, it is not uploaded. Java
