File in the same folder is not updated


When you copy a file, for example index.php , and in the same folder there is a index.php file I change the name before copying and puts the atom 2 with the same code .
I use Ubuntu 14.04 .
My English is not good, but I hope you understand .


I’m sorry, I don’t understand. Could you list individual steps that reproduce the problem? Or share a screenshot or two?
