How can I remove the default generated  tags in view's result? I am using a views in my drupal web site. I have set 'style' to 'Unformatted' and 'Row style' to 'Fields'

Also I have Rewrote the output of the field with my HTML tags.

But I have a problem in the result.
Every row is located inside a [div] tag
for example the first row is located in 

&lt;div class="views-row views-row-1 views-row-odd views-row-first"&gt;&lt;/div&gt;


How can I setup the view in order to remove this extra [div] tag ?!?!?

I don't need this wrapper.
The easiest thing to do is copy the template files from "sites/all/modules/views/theme/" into you theme (I normally make a "views/" subdirectory).

If you want to make this change for all themes, edit "views-view-unformatted.tpl.php".

If you want to just change that view, edit the view then click on the Theme: Information link.  It will show the template suggestions for the view.  Copy 
If you want to make this change for all themes, copy "views-view-unformatted.tpl.php" to the proper name, and edit that file.

In both cases, make sure you clear the Drupal caches to make sure the system finds the new files.
