An easy way to password-protect certain folders
To password protect a specific folder in any version of OS X, if you're an administrator, simply change the permissions in the "Get Info" box so that the folder is owned by the system. You'll be prompted for a password. To access the folder again, just change the ownership back - and it will require a password to be made accessible.
Secret Folder lets you conceal a folder and its contents.
