Connecting to MVS

Hi
I am a new user of WinSCP.
My problem is as follows.
When I am connecting GUI to MF my remote site is USS root. I want to get to MVS files, but do not know how to get there.
I try to click Remote and Change Directory, and to insert "MYUID.**" in place of / but still find myself in USS.
WinSCP 5.17.6
z/OS 2.4,
Please clarify.Thanks in advance.

Got it: I must enter the path in format 'MYUID.'
Maybe will be useful for new users.
