By default, Windows chooses to hide a good number of files from it’s users. Fortunately, it’s easy to turn the relevant options off!
Open My Computer or Windows Explorer.
- Go to the Tools menu, and select Folder Options…
- Select the View tab, and locate Hidden Files and Folders, select the sub item Show hidden files and folders by clicking on the check box
- Below this option, uncheck the box next to Hide extensions for known file types. This allows you to be able to see, for example, whether a file is a .GIF or a .PNG
