Location of dhtmlx.js??

We have purchased the pro version only of the grid (not the suite). We have dhtmlxGrid v.3.0 Professional edition build 110707. We’ve unzipped this file into a directory. The connector version that was sent with that was 1.0 so we have since downloaded the newest version (1.5). The problem is that the samples provided refer to a file “dhtmlx.js” but the only place that file is located is in:

Is this the file I should be using??

“dhtmlx.js” - is a file containing all components of standard dhtmlx suit.
You may use this file or you may include your files from “dhtmlxGrid v.3.0 Professional edition build 110707” instead of it.
But it is not recommended to include individual files AND compiled dhtmlx.js
