[PatrykKuniczak]

Describe the bug

There's problem with recognize promise which are return from fs-extra for couple of functions.

Another one:

Interesting thing is, that happend only for WebStorm, VSCode doesn't complaining.

I was trying to fix it in #2015 but this solution isn't good and i reverted it.

That's bizzare:

Let's see here, typescript doesn't complain:
