There are many more files on your computer than you are normally allowed to see. For instance, there are many system files, most of which are hidden for ordinary users. While this is very reasonable, having in mind that beginners often tend to mess up with system files unintentionally, which can cause Windows to stop working, if a system file is removed, deleted, or renamed, if you feel more advanced in Windows, you can select that these files are displayed in Windows Explorer. To unhide hidden files, go to Folder Options in Control Panel (or you can access it from the Tools menu in a Windows Explorer window) and open the View tab (you can have a look at this screenshot – HiddenFiles.gif). In the Advanced Settings pane select the radiobutton Show Hidden Files and Folders and that’s all.
