Get the Files Affected by an FTP Sync

Demonstrates the Chilkat Ftp2.GetSyncedFiles method, which reports the relative paths affected by the most recent synchronization. The only argument is a StringTable that receives the paths (uploaded, downloaded, or deleted).

Background: A sync call reports only overall success, but you usually want to know what actually changed — for logging, for triggering follow-up work on just the new files, or to confirm an incremental sync did the minimal transfer. An empty result is meaningful too: it means everything was already up to date. Call it immediately after the sync, before another operation replaces the recorded list.
