Disk Defrag

Hi I have a question regarding scheduel running of disk defragment
If I set the program to run in background does it mean the program still work if I turn off computer?
When I set scheduel running for the program, will it be working if the laptop is not open window?

В чем коротко отличие оптимизации от дефрагментации HDD ?

Please tell me why on earth your programme needs to unmounts two drives after the defragmentation process, the one (J:\) that has been defragmented and the other one (O:\) that was not touched by any process of the defragmentation. Only restarting the Win10 operating system made the drives be mounted again, even a partitioning programme (MiniTool) did not find the drives before restart! Next question: how do I prevent this from happening again?
Thanks for your well appreciated help.

Non riesco a deframmentare un hard disk da 6 Tb che è fermo al 72%.
Ho comprato la licenza credendo fosse quello ma non è successo niente.

Cordiali saluti

Me gustaria saber si en verdad es buena la version pro o si vale la pena pagar la suscripción ya que suelo usar tarjetas micro sd y no conozco a nadie que lo haya hecho. No se si tienen una prueba gratuita de esto que no sea la desfragmentacion simple.
