The Resume property will force wodSFTP to resume a file
transfer, if possible. The File transfer will not truncate
the destination file and data transmission will continue
from the point where the connection was lost last time.
If you are uploading a file, wodSFTP will start from
the position that is equal to the length of the existing remote file
on the server.
If you are downloading a file, wodSFTP will start
from the position that is equal to the length of the existing local
file.
