Images for kepubs and recommendations and things from Kobo, will have a 22 character id. From what I have seen, these are cleaned up properly. If you delete these, the device will still be OK, but a blank or a dot will be shown for the cover of these books.

The reason I was so blown away by the number of images was that a lot are books I've definitely never had on my glo. Some are books I've never even heard of. Or authors I wouldn't dream of reading.
When I did a simple search of files starting with "file", the only thing that came up was 7 images for 3 library books I currently have sideloaded on the main memory (2 I haven't opened yet, so don't have the biggest image file).
It takes my computer ages just to open all the thumbnails in the folder. So it's a bit time consuming to look at exactly what all is there. The properties say 4,959 items, totalling 176.7 MB. I had a few more when I had my sideloaded epubs on main memory, but calibre seems to have cleaned it up fine.
But I have only about 220 kepubs on my main memory (plus the 3 library books and 1 txt file). So even if I had all three images for all of them, it shouldn't be more than around 660 images. Even if calibre has also sent images for the kepubs that match an epub in my library (which I doubt it does) that shouldn't add more than 110x3 images, so still under 1000 images total. And based on what you're saying I shouldn't have most of those 4000 extra files?
I haven't gone into the kobo bookstore on my glo in ages (months) and I haven't gotten recommendations for almost as long (one of the firmwares stopped me getting images since my account has no bought books, now when I go into the bookstore screen it just shows a screen telling me that if i buy my first book, I get a discount...). So I'm assuming these images were collected quite some time ago.
They all have the 22 character ID which you describe, so it's pretty impossible to weed out ones I don't have the books for. But I'm not keen on having all my kepubs lose their covers, so I don't want to just delete them all. Any ideas?
