How do I override views-view-summary-unformatted.tpl.php inside my own theme? I cannot override views-view-summary-unformatted.tpl.php inside my own theme. I copy the tpl from the views module directory, paste into my theme directory and modify the code. My website will not recognize the new tpl. If I make the changes directly inside the views module, then I can see my changes on my website. However, I know it is not best practice to hack a contributed module. I've tried adding "--myViewName" to the tpl file, but this doesn't help. When I look at the Theme Information in my view, I don't see views-view-summary-unformatted.tpl.php listed there. (The reason I am trying to override this tpl is that I want my alpha bar to include all letters of the alphabet even if there are no entries for a particular letter.) Can someone please help me figure out what I am doing wrong? Thanks!
I know this is old but today I struggled with this and thought I should provide a solution.  

First, you have to rename your copy of 'views-view-summary-unformatted.tpl.php' so views can discover it. It should be named 'views-view-summary-unformatted--my-view.tpl.php'.  

You then need to click the 'rescan template files' button under the theme information in the view.
