This is the program which creates the image of FDD.
I want to change the program which copies the specified file.
And lose the start function after pushing key.
Where should I modify?
(ex;
a:\>dir
A.txt
B.txt
program.exe
a:\>program.exe A.txt(enter) <- Copy start
end
)
I am sorry to be an elementary question.
