If you are using Windows 2000 or XP and have the NTFS file system, you can
protect a single file by setting a password on it. Check under your Windows
Help for more information.
Setting encryption on single files isn't as secure as setting
encryption on directories. The OP wanted to encrypt a directory, that's
the most secure way to go, and Windows 2K and XP can do this. Right
click on the directory in Explorer, select Properties, click on the
Advanced button in the General tab, then check the Encrypt checkbox and
click OK. Follow the prompts in the subsequent dialogs. AND DON'T
FORGET YOUR PASSWORDS!
