A multi-content document has one document ID assigned, but the document consists of more than one electronic file. For example, you might have a proposal that contains both a word processing document and a spreadsheet document. For tracking and retention purposes, you would like to use the same name, the same properties, and the same location for this document, even though it consists of two files. You can do so by using a multi-content document to group the files. When working with a multi-content document, you have access to all of the files (subject to your security access).
You can add and remove content elements as needed, and each version of a document can have different files as content elements. That is, the content element files are associated with a specific version of the document. You must check out a document to add or remove content elements. When you check out a multi-content document, a reservation object is created for the new version of the document. This reservation object does not carry the multi-content information. That is, the multiple content elements are not automatically carried forward from one version to the next. When you check in the new version of the document, you must manually add each content element to the new document version.
Your site administrator determines which users can view the contents of a multi-content document and which users can save or delete content elements from the document. If you do not have appropriate access, you can only view the first element contained in the document. In other words, you would not know that the document contained other elements.
