how force the program to open specific directories each time i run it?

let's say i want to see c://myFolder on the left and /data/data/project on the right, and not the default c:// and /data

It's part of session settings:

Though by default, WinSCP will remember the folders, where you closed your session.
(See Remember last used directory)

i cannot find neither Advanced button nor Directories button, even in Login page

Does your Login dialog look like this?

Make sure you have the latest version of WinSCP.
