(in Sd Card) can i copy the entire file and rename it ?

When I tried to compile,I got this error:

When I try to compile, it works perfectly.

Of course, I am not compiling the same code as you are, since I haven't a clue what your code looks like.

Posting code in code tags makes you look smarter than posting code in quote tags, because code in code tags is not mangled by the forum software.
