' Upload synchronization modes:
' 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.
' 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.

' matching at least one pattern in a set.
