If anyone else in the world is going to read your code, e.g. you post your code on a programming forum, than you have to use descriptive variable names. If I told you that I had an array named @ten, and I asked you to guess what each element of the array was, what would be your guess? What are the odds you would be correct?

Your @one array contains file names, so how about naming it @file_names or @fnames?

In your opinion, what is the difference between these two lines of code:

$initialfile2 = $file;
$initialfile2 = "$file";
