Windows provides facility to hide files and folders so that no one can access it easily. You can hide any file by changing its properties. This is a guide to hide files and folders and then make them visible in Windows 7.
Right click on any file or folder icon and select properties.
In the properties window, on General tab, click on the box next to Hidden. Click OK.
Windows will ask you to select one option. Select the first one if you want to hide the folder only. Select the second option if you want to hide folder, its subfolders and files too. After selecting the option click OK.
Note: One can unhide the files or folders only by visiting the location on which you hide the file. Before hiding the files or folder, copy it inside the location which can’t be easily accessible (copy it inside a subfolder of a folder).
