If you want to specify this option after doing some documents transfer, you'll have to create the subdirectories yourself and move the retrieved files in working directory to the subdirectory, or you will get duplicated files. Before doing a request to a server, WebCopy checks for the file in the working directory, and sends file information to the server. Only if the file was changed since last access, the new version is retrieved. This option forces WebCopy to use the local copy of the file if it exists, without checking if the file was changed in the server. Webcopy displays a brief help, ignores other options specified and exits.
Some options conflicts with others.
