I understand this and I have done similar a few times (e.g. deleting all old emails, deleting all notes, deleting a tonne of old files etc.). It's quite freeing. We do hoard a lot of digital stuff that we really don't need. Saying that, there are a few times over the years I've needed somethings, realised I deleted it and regretted it. That feeling passed quickly though and I soon realised it probably didn't matter.
