Create a folder by date

[Maurits Knoppert]

I have a flow running that attachements from a certain e-maildress are saved in a folder of my OneDrive. 

At this moment I try to tweak the flow that the flow creates a folder by the received at dynamic content

But when I use that Dynamic content I get an error:

The problem is that there are some illegal characters in the folder name. The : is giving the trouble

Is it possible to only extract the date? 

I don't see any other easy to filter dynamic content to create a folder with

@Maurits Knoppert 

We are just starting with flows,

But we have the same question,

have you ever found a solution ?

update

found the answer, posting it for other newbies as me ;)
use an expression, for example :

utcNow('yyyy-MM-dd')
