Upload Directory Tree using a Plan

Chilkat FTP provides two methods to make it easier to upload large directory trees to an FTP server. The CreatePlan/PutPlan methods can be used to upload and resume an upload if an external failure occurs while the upload is in progress. The CreatePlan method recursively descends the local filesystem directory tree and creates a "plan" of all the files and directories that will be uploaded by PutPlan. The PutPlan method accepts a "plan", and keeps a log file of its progress as it proceeds. If PutPlan fails, it can be called again with the same log file to resume the upload.

//  If PutPlan fails while in progress, it may be called again

//  already uploaded and resume where it left off.
