remove Category name in shop by(left side) in magento

Open the file app\design\frontend\base\default\template\catalog\navigation\left.phtml in an editor and find the following lines:


  <dl id="narrow-by-list2">
            <dt><?php echo $this->__('Category') ?></dt>
            <dd>
                <ol>
                <?php foreach ($_categories as $_category): ?>
                    <?php if($_category->getIsActive()): ?>
                    <li>
                        <a href="<?php echo $this->getCategoryUrl($_category) ?>"<?php if ($this->isCategoryActive($_category)): ?> class="current"<?php endif; ?>><?php echo $this->htmlEscape($_category->getName()) ?></a> (<?php echo $_category->getProductCount() ?>)
                    </li>
                    <?php endif; ?>
                <?php endforeach ?>
                </ol>
            </dd>
        </dl>

Replace these lines with this:

<dl id="narrow-by-list">
<?php $_filters = $this->getFilters() ?>
<?php foreach ($_filters as $_filter): ?>
 <?php if($_filter->getItemsCount()): ?>
<?php if($_filter->getName() != "Category"){ ?>
<dt><?php echo $this->__($_filter->getName()) ?></dt>
<dd>
<?php echo $_filter->getHtml() ?>
</dd>
<?php } endif; ?>
<?php endforeach; ?>
</dl>
