How to create directory and move to this new directory

I want to schedule some commands on a daily frequency and create different directories every day (with the filename being the date and time), and upload some files afterward.
So I basically need something like:
Is there a way to do this?
Thanks in advance.

The simplest solution is just repeat %TIMESTAMP#yyyy-mm-dd-hh%. I understand that there's a small risk that "hour" changes between the two lines.

If you want to be 100% sure, you can query the timestamp before starting the actual script (based on Formatting Timestamp in Batch File):
And then in the script.txt WinSCP script, you can use %THE_TIMESTAMP% environment variable repeatedly.
Alternatively, instead of environment variable, you can use script argument.
