::思路：利用debug获得原文件16进制代码，然后再次利用debug构造生成原文件的bat代码。

setlocal

if not exist %f% (echo File doesn't exist!&&goto :eof)

::写临时文件
set len=%~z1
set/a end=0x100+%len%-1
call :10to16 %end%
pushd %tmp%
>t1 call echo d100 %%r%end%%%
>>t1 echo q
>nul copy %f% t2
type t1|debug t2|more|find ":">t3

::读取临时文件t3，获得16进制代码
