E2B TXT Maker.cmd        - generates an Easy2Boot .txt file
E2B MNU Maker.cmd        - generates an Easy2Boot .mnu file
E2B SUBMENU Maker.cmd    - generates a .mnu file from a \_ISO\xxxx new folder - use if you want a new SubMenu in the Main Menu
LZMA folder              - encode or decode E2B files such a MyE2B.cfg for security purposes
MD5 folder               - find the MD5 value of a string to use as an MD5-encrypted password
Fribidi                  - used to convert right-to-left language UTF-8 text files for E2B
Convert Unicode file to UTF8 - guess!

The easiest way to use these files is to first copy them to your Windows Desktop.

E2B TXT Maker and MNU Maker
===========================
Now to make a .txt file or .mnu file for any payload file on your E2B USB drive, simply Drag-and-Drop the payload file onto the E2B TXT Maker.cmd icon or the E2B MNU Maker.cmd icon on your Windows Desktop. 
The script will then ask you what menu text and help text you want and then make a new .mnu or .txt file (in the same folder as the payload file) on your E2B USB drive. 
You can specify a hotkey key by using ^^ before the keyname (^^ will be translated into ^ when the file is made).

E2B SUBMENU Maker.cmd
=====================
If you want to make a new SubMenu folder:

1. Create a new folder under \_ISO (spaces not allowed) - e.g.  \_ISO\RESCUE_WIN
2. Drag-and-drop the new \_ISO\RESCUE_WIN folder onto the E2B SUBMENU Maker.cmd file and answer the questions

OR double-click on the E2B SUBMENU Maker.cmd file and you will be prompted for the name of the subfolder that you want to create.

This will make a new .mnu file in the \_ISO\MAINMENU folder for \_ISO\RESCUE_WIN.
Now put your ISO files, etc. in the \_ISO\RESCUE_WIN folder and you will see the new menu entry appear in the Main Menu.
