Hiding a Folder in Windows Explorer

Want to hide your secret documents? Use the following steps to make a protected folder that cannot be accessed from the Windows Explorer:

Open the MS-DOS prompt, type mkdir followed by a space. Press and hold ALT, type 0255 (use the numeric keypad on the right side of your keyboard), and then release ALT. Now you can save your secret documents inside that folder. Windows Explorer cannot display its content. The only way to open that folder is by opening MS-DOS prompt, type cd followed by a space, press and hold ALT, and then type 0255.

You can also protect a usual (named) folder; just insert ALT+0255 as the last character of the folder name. Other ASCII characters that you can use to replace 255 are: 158, 159, 169, 176 to 224, 226 to 229, 231 to 240, 242 to 245, 247, 249, 251, 252, and 254.
