Many people do not know that in Windows Operating System, there are lots of hidden folders, like the System Folders. The reason why Windows did this by default is to prevent people from deleting them accidently. Some people create hidden folders to hide their important data from other users, especially when there are more than one people using the computer (public computer). Some people even tend to hide those files or folders which they might not like them to appear.
There is a special mini software known as Special Folders View which can help you to list out all your hidden folders in one place, giving you an overview idea where are those hidden folders located.
Those hidden folders that will be listed out including system folders such as temporary folders, storing application settings, temporary Internet files, program shortcuts to other files, etc.
As Windows user might not be able to find out those hidden files one by one and to do much with those System Folders, but this mini software can help, at least to track down if there are any unnecessary folders which were made hidden in their PC.
This utility works on Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista, and Windows 7. There is also a separated non-unicode download for Windows 98/ME.
