There has been a lot of wingeing over the loss of "All My Files" in favor of "Recents" in High Sierra, and I am beginning to understand why. For one, it seems to be an opaque tool and I have yet to locate any means of adjusting how it behaves or even learn what criteria make files appear there.
One thing I am sure of is that files which I have created in the last 24 hours (specifically, screen shots) do not appear there. These are not esoteric files like .plist files, but .jpg files that I have saved within my Google Drive folder. I have no idea why this file is being excluded from "Recents" but it does infer why screen videocaps created by Monosnap and saving them to some mysterious location with a mysterious name, which would seem to be a perfect opportunity for "Recents" to be useful except that it doesn't seem to work.
Is there any way to adjust how "Recents" works or learn what the criteria are for files to appear there
