// mode=4: transfer missing files or files with size differences.
// mode=5: same as mode 4, but also newer files.

// Additional files and directores can be excluded by setting the SyncMustNotMatch property.
// The SyncMustNotMatch patterns apply only to the final filename or directory part of a path.
// If a directory matches, then it will not be traversed in a recursive traversal.
