I believe u should Type

rm -r \'folder\'\$\'\\003\'

Basically a \ interprets the following character as a character. With the ’ I’m not sure, so maybe

rm -r 'folder'\$'\\003'

could do the trick too

Edit: correct code

As far as I can see, the contacts were been ripped off. You could try scratch away the coating in the lines above and try to get a connection there but I think you need some experience to do that
