I’m getting “Your file was uploaded — it’s safe and sound in Slack. Unfortunately your workspace doesn’t have any storage space left…” etc. Time to purge files again?

We run the purge script fairly regularly now, I believe, but we can't purge files shared in private DMs (not even the Slack owner can see private DMs), so we're stuck with a lot of old cruft that was uploaded by people who are no longer members of this community.

Ah, well I can definitely purge DMs. There aren’t many, but whatever I have.
