Get filename when right click

[MioKawaii]

I'm trying to use a CMD to do things when I right click on a file but how to get the filename of the file that I click on?

eg:

- I put a utility name base64.exe in windows\system32

- I right click on a file name 01.base64 reside in any folder and choose "Base64 Decode" (which is done through registry entry below)

HKLM, "%CLASS%\.Base64\shell\Base64Dec", , , "Base64 Decode"
HKLM, "%CLASS%\.Base64\shell\Base64Dec\command", , , "base64.cmd"

The base64.cmd contains the following code:

@echo off
:BaseDec
Mode 80,12 & Color f1
ECHO Please input the desire new output filename including the extention.
SET NewName=
SET /P NewName=Please input the desire new output filename including the extention.
base64 -d "%1" "%NewName%"
EXIT

:Base64En
base64 -e "%1" "%1.Base62"
EXIT

As you all can see, the %1 does not work here. Please help!

HKLM, "%CLASS%\.Base64\shell\Base64Dec", , , "Base64 Decode"
HKLM, "%CLASS%\.Base64\shell\Base64Dec\command", , , "base64.cmd"

I may have the syntax off slightly but perhaps you need a %1 in there:

HKLM, "%CLASS%\.Base64\shell\Base64Dec", , , "Base64 Decode"
HKLM, "%CLASS%\.Base64\shell\Base64Dec\command", , , "base64.cmd %1"

Thanks! But how do I go to a certain LABEL in this base64.cmd file from the registry?

I'm guessing that you'll need to create more logic in your batch file for it to do what you want it to do.
