 My addition to that is the form with =evil-numbers/inc-at-pt=.
+**** Archiving records
+- *CREDIT*: thanks [[https://emacs.ch/@grinn][Amy]] for pointing me to the right functionality of =org-refile=.
+
+I have several org files for long-running projects. They are getting hard to manage because there are lots of different tasks, events, etc.
+
+So I want to create "archive versions" of these files which would have the same structure but store items, say, with a timestamp older than 2 months.
+
+Archive versions are to be stored in the =archive= subdirectory relative to the current file, e.g., =foo.org= -> =archive/foo.org=:

+    archive-file))
+#+end_src
+
+In order to maintain structure, we need to make sure that the archive version has all the necessary headers.
+
+=org-refile= (or, to be precise, =org-refile-get-location=) by itself can create the last level of headers with =org-refile-allow-creating-parent-nodes=. So I can just invoke the same logic for all missing headers:
