Bear in mind that at this time, and for many years, data retention policies simply do not apply to uploaded files in a given channel (IIRC it does apply to global retention, but I'm not totally sure of the current behavior). There's a sensitive channel with a short retention period in a Slack for a company I do some consulting for and every few months I remind the admins that images/PDFs/etc that are uploaded to the channel are not purged and they should manually do it... but there's still stuff in there from 2016 if I do a search in:#channel for Files.

It sounds like there’s no file retention policy specified for that Slack workspace. It’s possible to set a policy specifically for files.

Right, the issue is that it's not possible to set file retention for individual channels/conversations, so if you want to have long-term file retention in some places and brief in others, it can't be done (additionally (in my experience, at least), people tend to believe that setting message retention will also apply to files -- it's not called out in the interface/etc).
