There have been many batch files that let you password protect a folder, I even made a few to use. But the problem with all of them is that anyone who has access to that batch file can right click on it and see the password written in it.
So after many hours of thinking I came up with a solution, "REMOVE the PASSWORD from the batch file".
And the result was LOKEY v1.0, it has the following advantages over other batch file:
1) The password is not stored in the batch file.
2) You can create as many secret folders as you want.
3) You can use it from any directory.

So lets see how it's made.

Step 1: How It Works

Step 1. Place it anywhere on your PC.
Step 2. Double click on it.
Step 3. Enter a to create a Folder, b to hide an existing folder or c to unhide an existing folder.
Step 4. Enter a folder name and password.
Step 5. Enter.

Since you guys are making batch files, I assume that you can fully understand the code and it's working.
It is like my other batch codes really simple, since I don't know much about anything.

So next is the code, use it and comment about any problems or any changes that you might have made.

Step 2: Code Goes Here

Copy and paste the following lines in Notepad and save it as anything.bat

Save it as anything.bat

Note. I've tested it in my XP. If you find some problem in finding the WINDOWS Folder, just change all the bold test with the path to that folder.
You can also change that path to any folder you want to keep the Lokey Folder in.
