Used the IDMan.exe command line to queue twelve large archive parts silently and had Windows Task Scheduler launch the batch at 02:00; silent mode started a test download immediately with no dialogs, and /p and /f gave exact destinations for every item.
- What worked
- The /n silent flag starts downloads right away with no dialogs, so a plain batch script can queue many files headlessly; /p and /f make destination folder and filenames deterministic; the end-to-end test file landed safely in the right place within seconds of the command.
- What got in the way
- Command-line flags are only described on a support FAQ page and some are easy to misread (/q quits IDM when the download finishes; /a only queues without starting); there is no CLI way to pause or stop downloads that are already running, so adjusting a started batch needs the GUI.
