What is "processing" doing in the current folder window?

Hi

I've just found "processing" never ends and freeze the Matlab. Does anyone know what is the "processing" doing and how to fix it?

OS: Mac High Sierra Version: Matlab 2017b

Shouldn't this be converted into an answer?

I can't believe I'm telling Walter off!

Please write the same thing in the Answer window so that I can make it as an accepted answer.
