An asset (shared content) is a file that stores a piece of page content such as an image or an event description. To display an asset's content on a page or template, you insert it into a widget. The asset content looks the same as local content (that you enter directly onto a page or template), however assets have a different function than local content. Assets enable you to include the same content on multiple pages or templates on your website.
For example, when you issue a press release, it usually contains a brief blurb about your company and who to contact for more information. Job openings usually include equal opportunity disclaimers. Rather than retyping this information for every new page, you can create assets to include this content, then add the appropriate asset to each page.
Using an asset reduces the amount of work you need to do to maintain your content, because when you change the content of the asset, the content is automatically updated on all pages that use the asset. Using assets to share content also reduces the chance that errors will occur when the same content must be changed on multiple pages.
Note that forms and binary files are automatically treated as assets. While you must create other types of assets manually, form and binary assets are created automatically when you save their widget content.
You create, edit, and delete assets in the Finder, which displays their folder structure in your system. You create binary assets either in the Finder or when you create content in a widget that uploads a binary file. From the Finder, you can drag and drop assets onto pages and templates.
