No, you can't use TechScheduler for FTP operations because this is just an application used for scheduling different Windows activities. To schedule FTP transfer based on your filters, a dedicated FTP application needs to be used. In this case, FlashFXP is a good choice. There is also a guide on how to set it up for scheduling. You can download a copy of the software from the official website, but take notice that it's shareware and it needs purchasing after the trial is over.
