Your web files have special needs because anytime you move or delete a file, it has an effect on other files that are linked to it. So, Dreamweaver also has file management tasks related to the web development environment. Dreamweaver keeps a record of all the links on your site. (Remember that the code for a photo is also a link.) Then when you move, Dreamweaver will ask if you want to update the other pages that link to that file. If you delete a file, Dreamweaver will warn you, if there are other pages using that file. Dreamweaver is actually a package of programs and one of them does the file management tasks.
