You have several different ways of doing this :-
You could use the QSHELL environment (you will need access to your windows server as a share).
Or you could use FTP (but this isn’t a very practical way).
In either case you will need to run some sort of script. You can either create a permanent script which you can run each time, or you can create a new script each time based on parameters. Your choice of which way to go with this will depend on the tasks the script needs to do. In your example you need to create a new folder, if you need to specify a different name for your folder every time the script runs, then you’ll probably need to build a new script each time (with the name for the new folder in it).
