Packaging the project
When you place content in InDesign, a relationship is created between InDesign and the placed Photoshop document. When you finish your project, it is recommended that you package all the linked assets together to create a project backup or archive. When you create a package, the following actions are performed:
A folder is created that holds:
A duplicate of your project file
A subfolder that holds a copy of all linked content
A subfolder that has a copy of all the local fonts used in the document
All links in the duplicate project (in this case, the InDesign document) are relinked to the copied links in the newly created subfolder.
The main advantage of packaging your work is that it creates a standalone version of your project with its own version of the linked files. This means that accidental changes to linked artwork will not affect your main project.
From the Lesson03 folder open L03-poster-end.indd.
Choose File > Package.
Optionally, review all information to verify what will be included in the package.
Click Package. If a dialog box opens asking you to save your file, click Save.
In the Create Package Folder dialog box, name the folder poster-package.
If you want, add a PDF version of the document and/or an IDML version by selecting the appropriate options. IDML documents can be opened by those who are using an older version of InDesign.
Click Package to create the package.
