Uipath FTP Activities

I’m having some difficulty in establishing the procedure to connect to FTP server, and choose thru the day, at different time slots (4 Slots: 10 AM, 1 PM, 3 PM and 5 PM).
I need to enter in 93 diferent ftp root directories, and in each, choose the latest csv file, download them to my Onedrive directory.
How shall i do it? Shall use config file, open process activity, open application activity?
I use Winscp or Filezilla to connect to FTP server.
Help please
