The attachments object contains information about attachments associated with a record.
You can upload attachments against nearly all records in Current RMS. They're generally used for files that are associated with a record, for example:
PowerPoint presentations, configuration files, or information sheets related to an opportunity.
Floor plans or photographs associated with a venue
Photographs of damaged goods for a quarantine.
Remember that when using the attachments object, you can include images but you can't embed other kinds of files into a document layout or discussion template. Instead, you can hyperlink to link to them.
Attachments may contain commercially sensitive information, so be sure that you’re not inadvertently sharing attachments that you don't mean to on a document layout or discussion template.
