-a network share. Place it before the first analysis/transcode node; it records
-the library path for `replaceOriginalFile` 2.0.0.
-Both progress-enabled copy operations verify the destination size and retry
-failed writes twice after removing the partial destination. Their `Copy method`
-uses the operating system's native file-copy path, reports interval speed,
-verifies the destination size, and retries failed writes.
-Both progress-enabled plugins require
-`FlowHelpers/1.0.0/copyWithProgress.js`; the installer downloads it
-automatically.
+`copyToWorkDir` è facoltativo ma consigliato quando la libreria sorgente si trova su una condivisione di rete (NAS/SMB).
+Posizionalo prima dell'analisi/transcodifica: registra il percorso originale della libreria per `replaceOriginalFile`.
+Entrambe le operazioni di copia/sostituzione trasmettono la percentuale di avanzamento alla WebUI di Tdarr tramite il worker callback,
+registrano velocità ed ETA, verificano l'integrità del file per dimensione e supportano il retry automatico.
+I plugin utilizzano `FlowHelpers/1.0.0/copyWithProgress.js`.
