Synchronize Local Directory Tree

See more FTP Examples

Downloads files from the FTP server to a local directory tree. Synchronization modes include:

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. Ruby
