Do Archive, Purge, and Restore Files Include Attachments?

Summary:

Do Archive and Restore Files Include Attachments?

Content (please ensure you mask any confidential information):

The documentation doesn't seem very clear in this as it only says "related data". If I archive and then purge a period, what happens to the attachments? Do they get archived as well and removed from the application? Will they restore if we restore the archive? What about if we are using Object Storage? Are they purged from Object Storage? If not, do the links get reestablished if we restore the period?
