How to Unhide a Folder on Windows 7
This article shows you how to see hiddeen files and folders in Windows 7. Windows 7 hides important system files so that normally, you do not see them while exploring your computer.
The reason behind hiding these files is that users could inadvertently tamper with them or even delete those causing Windows 7 operations to falter. However, malicious software programs take advantage of this feature to create hidden files or folders and cause disruptions in the computer's operations without the user being able to detect them.
Therefore, being able to see hidden files or folders has its advantages and helps in repairing damages caused by unwanted hidden files. You can change the behavior of your Windows 7 computer to show hidden files by changing the settings in the Folder Options screen. There are two primary ways you can reach the Folder Options screen. Start by closing down all open applications.
