To view hidden folders on the computer, you need to go to the control panel, folder options, there is an option to view hidden files, just open it. If you use a mobile phone, download a file driver, or X manager (which needs to be signed or cracked). The dictionary that comes with the mobile phone is not easy to use. Go to Saipan to find the Cambridge dictionary, and I will use it! Mobile phone call, hope the landlord will adopt it!
