350-2 Opening and exploring data

I have an issue but in the guided project Profitable App Profiles for the App Store and Google Play Markets.

FileNotFoundErrorTraceback (most recent call last)

7 read_file = reader(opened_file)
FileNotFoundError: [Errno 2] No such file or directory: ‘Applestore.csv’

The two apostrophes around Applestore.csv are not normal apostrophes. Did you type them on an english keyboard or while another language is turned on, or pasted it from somewhere else?
