As a business owner or client, it would be outside your expertise to remember the file formats of the logo and however your logo designer knows what file works best for what purpose very easily. You could request your freelance logo designer to give a brief of the details of each file many would be ready to help but if you have designed a cheap freelance logo designer then they will not be providing all the file formats needed for your marketing.
