To keep a package together. A report can carry the spreadsheet behind its figures, a tender document its supporting certificates, an invoice its itemised data. Everything travels as one file, so nothing gets separated when the document is forwarded or archived.
Most desktop readers show an attachments panel, but support is uneven — some mobile and in-browser viewers hide attachments entirely, so a recipient may never realise they are there. Mention the attachments in the document text rather than assuming they will be discovered.
The file grows by roughly the size of what you attach, since the contents are stored inside. Attaching a large video or dataset produces a PDF that is awkward to email — which rather defeats the purpose. It works best for modest supporting files.
