When a file is deleted, it is moved into the archive. It will remain in the archive until it is either permanently deleted (DELETE:archive/files/{fileid}) or restored (POST:archive/files/restore/{fileid}).
Use GET:files to retrieve a list of files across the site or GET:pages/{pageid}/files to retrieve the files on a specified page.
