Hide files in Windows (XP or Vista)

Probably already know how but here's a tip for those who not know.
In many situations of our lives we want to have more privacy in our own computer or even working, for widely varying reasons such as; have content in our computer that we want our children not to see or work files that should be important not to move, there is a simple way to hide those files; we imagine that we are in "My Documents" and have a folder named "Important", if you click over the folder with the right mouse button will have an option that says "Properties "when you click "Properties " will open a table and in that table below is an option that says "hidden" by clicking this we have to Make apply, then will open a new table to ask if we want to hide a folder or the folder that is inside, here the choice is yours but I always hide the folder that is inside. In this step, the file is already hidden. We will never forget where the file was in, this instance was in "My Documents". To display the folder again we go to “My Documents” and from the menu click on “Tools” and then “Folder Options” Click on the “View “ tab and under the “Hidden Files and Folders” section, choose the radio button that says “show hidden files and folders”. and clicked and then we apply. Now the folder “Important” appears again, we can access files as usual, then to hide again you do the same procedure as mentioned, from the menu click on “Tools” and then “Folder Options” Click on the “View “ tab and under the “Hidden Files and Folders” section, choose the radio button that says “Do not show hidden files and folders”.
I hope I have helped
