    Only one tru solution here and that is Truecrypt. It is one of the best, if not the best “hiding” tool.

    Oron already mentioned this, but it needs to be restated as a warning. If the data is important/sensitive, do NOT rely on attribute changers. Simply checking a box in folder options nullifies that method.

    On every install of Windows I’ve ever had, I have immediately set Explorer to “Show all files”. Force of habit, I don’t like knowing there are hidden files scattered around that I’m unaware of.

    Open a Command Prompt Window by clicking Start->Run->cmd

    Navigate to the location where your folder(the one you want to hide) is.

    To hide your folder, type:

    attrib +h +s foldername

    To Un-hide your folder, type:

    attrib -h -s foldername

    You will not see or be able to search for the folder even if you have Show Hidden Files checked.

    A good and highly secure option is to use the free utility TrueCrypt (, which allows you to create a ‘fake’, encrypted hard drive within your hard drive. It provides a number of ways for you to do this, from hiding a partition to creating a ‘soft’ hard drive in the form of a large, randomly named file, hidden somewhere in a random folder.

    Just don’t forget the password. :p

    Here are two possible approaches:
    1. Mark the folder as hidden using Windows’ own “hidden” attribute. This will only work if the PC is configured NOT to show hidden files…
    2. Use a folder hiding program such as “Free Hide Folder” from

      #2 wouldn’t work on another system, surely?

    • Oron

      Erm, you’re right! My bad.
      However, there are portable equivalents such as WinMend and Folder Lock 7. Security is provided by encrypting the folder with a password.
