When I try to open them with Notepad +++, they look something like this:

ÿÿÿÿÿÿÿÿ`ÀÆóëËÕ|‘[$4Ú¤Yîß u

In SublimeTex, it looks like this: 0001 0001 0000 0000 0000 001b 0000 001a 0000 0000 0000 0000 ffff ffff ffff ffff

>Hello, I am looking at the files for a web page that uses PHP and Cake, and I see a number of files use either a .i extension or that with end with .cpt.i . However, when I try to open these with Notepad +++, for instance, the contents is encrypted? Is there a way to open and edit .i files? Is it possible that these files are encrypted? If so, is there any way to un-encrypt them? But maybe I am getting ahead of myself.
