Error using copyfile (Cannot copy or move a file or directory onto itself)

I am trying to copy a file with name test_0 and paste it in same location with name test_1. Then i want to repeat this code with the numbers increasing by one in the file name. I wrote this code:

for i=1:100
Filename=strcat('test_',num2str(i));
Filename=strcat(Filename,'.xlsx');
FilenameR=strcat('test_',num2str(i-1));
FilenameR=strcat(FilenameR,'.xlsx');
copyfile (FilenameR),(Filename)
end

and i am getting an error:

Error using copyfile

Cannot copy or move a file or directory onto itself.

Error in File (line 19)

copyfile (FilenameR),(Filename)

What can i do.

I think the syntax is just supposed to be

copyfile FilenameR Filename

"I think the syntax is just supposed to be copyfile FilenameR Filename"

Nope, that won't work:

Your copyfile sytnax is incorrect. Try this:

copyfile(FilenameR,Filename)
