SFTP Upload - Synchronize Directory Tree

See more SFTP Examples

Demonstrates how to upload files to synchronize a local directory tree with a remote directory tree. The SyncTreeUpload method recursively descends a local directory tree and uploads files based on existence, last-mod date/time and/or size differences.

    //  The local directory is relative to the current working directory of the process.
    //  It is also possible to use absolute paths.

    //  Possible modes that can be passed to the SyncTreeUpload method are:
    //  mode=0: Upload all files
    //  mode=1: Upload all files that do not exist on the server.
    //  mode=2: Upload newer or non-existant files.
    //  mode=3: Upload only newer files. If a file does not already exist on the server, it is not uploaded.
    //  mode=4: transfer missing files or files with size differences.
    //  mode=5: same as mode 4, but also newer files.

    //  This example will use mode 5 to upload missing, newer, or files with size differences.
