In a template: Is there a way to call the parent's folder name? For Structured entries, I always have about the same folder structure. 
If I could access the parent's folder name, I woudn't have to change the {% includes %} when copying a folder. 

e.g.:

blog
---_common
---_entry
---_listing
---index  

so _entry looks like this: 

{% extends "_layouts/_layout" %}

{% block content %}
    {% include "blog/_common" %}
{% endblock %}


and _listing looks like this: 

{% set params = { section:'blog', limit: gl_config.cf_blog_limit} %}
{% paginate craft.entries(params) as entries %}

    {% for entry in entries %}
        {% include "blog/_common" %}
    {% endfor %}

    {% include "_includes/_pagination" %}

{% endpaginate %}


They look almost the same for every structure channel I use (e.g. discography, pressreleases, projects etc etc.) 

If I could use {% include "PARENT_FOLDER_NAME/_common" %}

I could just duplicate the folder and don't have to worry about these templates! 

btw: the _common template looks about like this: 

&lt;article class="listing_item format"&gt;

    &lt;div class="listing_heading toggle_content"&gt;
        &lt;div class="listing_heading_date"&gt;
             &lt;span class="h1"&gt;{{ entry.postDate | date("d") }}&lt;/span&gt;
             {{ entry.postDate|date("F Y") }}
        &lt;/div&gt;
        &lt;div class="listing_heading_title"&gt;
            &lt;h1&gt;{{ entry.title }}&lt;/h1&gt;

            {% set tags = entry.cf_blog_tags %}

            {% if tags | length %}
                {% for tag in tags %}
                    {{ tag.name }} 
                {% endfor %}
            {% endif %}         
        &lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="listing_content"&gt;
        {# 
            Content Matrix text / images / files / quotes / slideshows / videos etc..
        #}
        {% include "_includes/_content_blocks" %}

        &lt;p&gt;&lt;a href="{{ entry.url() }}"&gt;Permalink&lt;/a&gt;&lt;/p&gt;

        {# Edit #}
        {% include "_includes/_edit" %} 
    &lt;/div&gt;
&lt;/article&gt;
Have you tried setting a variable and passing it down into your include?

{% set parentFolder = craft.request.getFirstSegment %}


Then pass parentFolder (or whatever you name it) down? This of course assumes your first segment is the name of your folder tree.
