Windows hides certain files so that they are not able to be seen when you exploring the files on your computer. The files it hides are typically Windows System files that if tampered with could cause problems with the proper operation of the computer. It is possible, though, for a user or piece of software to set make a file hidden by enabling the hidden attribute in a particular file or folder's properties. Due to this it can be beneficial at times to be able to see any hidden files that may be on your computer.
To enable the viewing of hidden and protected system files in Windows, please follow these steps:
When the control panel opens you will see a screen similar to image below if you are using Windows 7.
Now click on the Show hidden files and folders option as shown by the red arrow in image 2 above.
Windows will be configured to show all hidden files.
