Yes it is, though you can change them if you so desire. I dont mind all the generic icons, since I jsut read the file names. We can tell you how to change them, though it is a bit of work, though you can change the default icon I think...

P.S. To change the icon, right click on it and click "properties". Go to the general page, and next to icon, there should be a change icon button. CLick it, and you can choose the new icon from there. If you want a different one, there should be a browse button to select manually.
