    Password protected directory?

    Would it be possible to write a program that protects a directory in windows so that if you click on it, it will ask for a password before you can access it? Or is there already a program on the net that can do that?

    Hmm... Cool prospect. I would say No, Unless You Rewrite Windows, but there may be a way to work around it.
    Compilers:
    GCC on Red Hat 8.1 (Primary)
    GCC on Mac OS X 10.2.4 (Secondary)

    Others:
    MinGW on XP

    I'd say it's possible.

    In the registry, the program used to open every file-type is stored. The program used for folders (default: explorer) is also stored there.
    Perhaps you could associate your program to folders and redirect the request to explorer if the password is correct.

    This feature exists in Windows NT/2000/XP as NTFS access control, but it's not very smooth to use as you describe.

    I idn't know it stored it in the registry.

    I assume it is in HKEY_CLASSES_ROOT, but what is the key?

    Biosninja, there are plenty of registry tutorials out there, and a good reference for registry stuff is regedit.com (which just moved to http://www.winguides.com/registry/).

    maybe you could do something we all know is possible, encrypt the files in the directory, you could make that proggy

    Nope. I don't want to decrypt the files/directory everytime I want to access it. he directory will also be big (about a gig or more). It will take a lot of time to encrypt and decrypt it every time

    win 2k+? yes, quite easy to do by hand; to do through a program shouldnt be too hard (i have very little knowledge of windoze-specific programming), but of course to run this program you would need certain user privelages already.
    earlier win? no easy way.
    hello, internet!

    And when someone runs a command prompt and then goes into the directory, will that be OK?
    Demonographic rhinology is not the only possible outcome, but why take the chance

    Nope. It should then say access is denied or ask for the pasword

    Well then blocking access through explorer probably isn't going to give the desired result.

    This will be implemented internally using encryption accessed via permissions and/or password in the next Windows Desktop build

    The only ways i see:
    1) Encrypt some simple way and make a program that decrypts it

    2) Make a program that acts like explorer, and disable msdos prompts (PM me on how to do this)

    3) Rewrite some part of windows
