View Hidden Files and Folders on Windows
To view a hidden file or folder on Windows 8 or 10, click the View tab on the ribbon at the top of the File Explorer window and enable the Hidden items checkbox under Show/hide. Hidden files and folders will have partially transparent icons, so you can easily tell which are hidden and which are normally visible.
On Windows 7, click the Organize button on the toolbar and select Folder and search options.
Click over to the View tab and select the Show hidden files, folders, and drives option. Click OK or Apply to save your changes.
