How to use WinRAR to save encrypted folders

I always wanted to encrypt my folders, and when I saw the method of encrypting by editing a folder's property template in the computer newspaper, feel simple and convenient, do it right away: When the folder you want to encrypt is opened, right-click, select Custom folder, and select or edit the HTML template for this folder to tick , Next, "Edit the template" tick, Next, Notepad opens the Folder.htt file, finds the first one, added below:

var passs=prompt "Please enter a password"

If pass= "ABCD"

Window.location= "E" 

Then save the file, and then "Finish", a dialog box appears, asking for a password. I entered "ABCD" but appeared in e-disk File window, what's going on? Now you want to edit folder.htt. I have important files in my folder. Then I suddenly remembered that I have seen the article that winrar can save damaged documents, then try it. Run WinRAR, select the encrypted folder, see folder Settings folders, double-click Open, Folder.htt files in them, and edit. A look, the original in the input, because too excited, the password lost into the "AABCD" no wonder! Try with the new password, the encrypted folder can be accessed.
