@BYK - I’ve extracted the DebugInformationFile stuff from my cleanup project: https://gist.github.com/rodneyrehm/8611730c8461befd0152da54b9e2de32 - It’s a trivial time-based approach. I doubt this will work for everyone.
I suppose something like “delete all DebugInformationFiles that haven’t been used for $x days” would be a safer bet - but currently those access times are not tracked/exposed…
