I am trying to do a manual upgrade from 1.2.9 to 1.2.10 which I am doing with an off-line clone before installing on the website, as recommended. This I am doing on Windows with Mysql and IIS installed with PHP, so I have the right environment. One of the steps is to copy new files to replace old ones and add new ones. Some of the new ones have strange names, but when you look inside them, they are just php files. For example guest_step_1.tpl0000664 or in the extension default-pp_express entensi0000644 There must be some tool which converts these to proper php (or tpl) files, but simply copying won't do it. What am I missing?
