there is ./back directory in my public_html directory of 184.108.40.206 Do I need it? Inside there is .back/app/Mage.php which is still old 1.8 version. Besides, the /back directory contains bunch of magento package files like skin, shell, app, media, defaults etc. I don't remember how this directory got there. Can I just delete the /back and everything inside? Is it just a simple worthless duplicate? Or does it carry any function? It bothers me because it's contains still some old insecure 1.8 version files. Thank you, Maks
There is no folder named back in the Magento CE 1.x release code root folder.
Sounds like this is a backup folder manually made by someone. It is safe to delete it.
I would keep a copy of it somewhere just in case.
