Option in [InstallDelete] to postpone deletion (or to Move instead of delete)
When installing an update I like to sequester the old version (can do), and after that would like, for neatness, to delete any old version files that aren't replaced by or part of the new version (don't see how at present).
By "postpone deletion" in the title, I mean a way to have the deletion of [InstallDelete] delayed until after a directive in [files] creates an archive copy. The documented (& actual) behavior of [InstallDelete] is that deletions happen before any copy directive in [files], hence the copy ends with nothing left to archive.
Thanks for the advice about newsgroups. I have; no reply yet.

Your title doesn't seem to match the question. [InstallDelete] answers the question. Also, it's best to discuss these queries in the newsgroups before posting here.
