A structurizes file is where you can see the different sections, divided by —- lines and other clear characters, where every new command is a new line. For example my file starts like this in WordPad:
# WordPress MySQL database backup
#
# Generated: Tuesday 16. May 2006 12:27 CEST
# Hostname: localhost
# Database: xxxxxxxx
# ——————————————————–
# ——————————————————–

# ——————————————————–
#
# Delete any existing table wp_categories
#
DROP TABLE IF EXISTS wp_categories
;
#
# Table structure of table wp_categories
#
CREATE TABLE wp_categories
(
cat_ID
bigint(20) NOT NULL auto_increment,
cat_name
varchar(55) NOT NULL default ”,
category_nicename
varchar(200) NOT NULL default ”,
category_description
longtext NOT NULL,
category_parent
bigint(20) NOT NULL default ‘0’,
category_count
bigint(20) NOT NULL default ‘0’,
PRIMARY KEY (cat_ID
),
KEY category_nicename
(category_nicename
)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 ;
#
# Data contents of table wp_categories
#
that’s a decent structure. Then you have lines that start with INSERT INTO, followed by the place they belong to. (categories, comments, …)
