Objective-C

Execute an FTP Upload Plan

Demonstrates the Chilkat Ftp2.PutPlan method, which executes a previously created upload plan. The first argument is the plan text and the second is the local path of a completion log that records each successful operation.

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: The completion log is what makes plan execution resumable: each successful upload is recorded, so if a run is interrupted, re-executing the same plan skips the operations already logged and continues where it left off — invaluable for a large transfer over a flaky connection. The plan's stored absolute remote paths are used regardless of the current remote directory, so execution is independent of session state.
