You can view the attachments for a work item and add new attachment objects if needed. The attachment can be either a single object or an array of objects, such as a document, a folder, a stored search, a search template, a publishing template, or a workflow definition file.
If the attachment is a folder, the complete contents of the folder can be accessed by anyone processing the work item. The folder contents are not considered part of the attachment and are not listed as attachment objects.
For example, the ExpenseReport workflow includes 2 attachments named ExpenseForm and ExpenseReceipts. ExpenseForm is a single object, assigned the ExpenseForm.xls spreadsheet by the workflow definition. ExpenseReceipts is a placeholder for you to assign up to 5 scanned image files of physical receipts.
The person who designed the workflow decides how many attachments are needed and when the objects are assigned to the attachment. That is, either the objects are assigned at design stage, or you can assign objects to an attachment while the workflow is in process. Additionally, the workflow designer can make some attachments read-only so that you cannot change the object assigned to the attachment.
If the attachment is a collection of objects, you can add more objects than the designer planned for. For example, you might have 6 receipts (instead of 5) to add to the ExpenseReceipts attachment from the example above.
