+`Directory Dialog`:index:
+******************************
+
+Use the Directory dialog to define a directory. A directory allows
+superusers to create an alias for a file system directory path that can be used
+by database objects. The directory does not store any database objects itself
+but provides a reference for accessing the file system.
+Please note that directories are supported when connected to EDB Postgres Advanced Server.
+For more information about using directories, please see the EDB Postgres Advanced Server Guide, available at:
+
+   http://www.enterprisedb.com/
+
+
+The *Directory* dialog organizes the definition of a directory through the
+following tabs: *General*, *Definition*, *Security*, and *SQL*.
+The *SQL* tab displays the SQL code generated by dialog selections.
+
+.. image:: images/directory_general.png
+    :alt: Directory general tab
+    :align: center
+
+Use the fields on the *General* tab to specify directory attributes:
+
+* Use the *Name* field to add a descriptive name for the directory. This
+  name will be displayed in the tree control.
+* Select the owner of the directory from the drop-down listbox in the *Owner*
+  field.
+
+Click the *Definition* tab to continue.
+
+.. image:: images/directory_definition.png
+    :alt: Directory dialog definition tab
+    :align: center
+
+* Use the *Location* field to specify an absolute path to a directory that will
+  use to alias.
+
+Click the *Security* tab to continue.
+
+.. image:: images/directory_security.png
+    :alt: Directory dialog security tab
+    :align: center
+
+NOTE:- This *Security* tab will be only available for EPAS 17.
+
+Use the *Security* tab to assign privileges for the directory.
+
+Use the *Privileges* panel to assign security privileges. Click the *Add* icon
+(+) to assign a set of privileges:
+
+* Select the name of the role from the drop-down listbox in the *Grantee* field.
+* The current user, who is the default grantor for granting the privilege, is displayed in the *Grantor* field.
+* Click inside the *Privileges* field. Check the boxes to the left of one or
+  more privileges to grant the selected privileges to the specified user.
+
+Click the *Add* icon to assign additional sets of privileges; to discard a
+privilege, click the trash icon to the left of the row and confirm deletion in
+the *Delete Row* popup.
+
+Click the *SQL* tab to continue.
+
+Your entries in the *Directory* dialog generate a SQL command (see an example
+below). Use the *SQL* tab for review; revisit or switch tabs to make any changes
+to the SQL command.
+
+Example
+*******
+
+The following is an example of the sql command generated by user selections in
+the *Directory* dialog:
+
+.. image:: images/directory_sql.png

+
+The example shown demonstrates creating a directory named *test*. It has a
+*location* value equal to */data/dbs*.
