Unless your pages are created from a Template page (.dwt extension), then you will ahve to go into each individual page and manually correct the links to point to the correct resource. A Template page allows you to create a "template" that the rest of the pages of your site will be based off of. Within the template you define areas for page content (the areas where each page will be different). Then you start creating pages based off the template. Whenever you make a change to theTemplate, all the child pages based off that template will get updated (except the areas you defined for page content). When editing pages based off a template, you'll notice grayed-out areas of code - this is code that's locked down by the template and can't be edited within the child pages.
But before using Dreamweaver Template pages, please review the Dreamweaver help files and read about them - we have many people come to these forums who have gotten very lost trying to use templates so please do read and learn about them before using them.
i am not using a template,
i just created one page and then save it several times with different names.
for example now , i had to makde a change in the "Spy menu" i added a menu
it only updated one page , but not the rest.
That's why it isn't updating then. The function you describe in your original post is one of the Templates feature in DW.
DW only knows to update pages made from a template when you change the template.dwt file that is attached to them. Otherwise changing links on one page will have no connection to the same links on another page. DW would have no way to know they are connected unless you use the Templates feature.
Unless you meant something else in your original post.
If you put your menu into a server-side include file, you can have one menu that populates to all your web pages.
SSIs are a huge time saver and very efficient because you only need to edit & upload one file instead of every page in your site.
Thank you for all your help.
After alot of reading about Templates i know now how it all works
