Kobo Touch Covers not appearing

[BlackVXGTS]

Hi Everyone,
My first post on this forum, I hope that you can help me. I've read the other posts in this forum that involve problems with covers but they don't seem to fit into the problem I am having.

I use Calibre to transfer most of the books to my Kobo Touch. This hasn't been a problem and all of the covers have been faithfully reproduced on my Kobo touch except for yesterday when I seen to have exceeded some Kobo internal limit.

I currently have 1342 books in my Calibre eBook library. By trial and error I found that when I exceeded around 1200 eBooks, any further additions didn't have their covers appearing on my Kobo Touch. Once the eBooks are transferred to Kobo, I can display them on Calibre and the covers appear OK. However, once I disconnect the Kobo from the computer and it finishes it's housekeeping, the covers only show the standard book icon.

I can delete eBooks from Kobo to take me below the 1200 (approx) limit and transfer eBooks that had previously appeared without covers, disconnected, waited for the Kobo to come back online, and their covers are now OK. I've also tried transferring eBooks to an SDC card rather than the main storage but it makes no difference.

In summary, the only reason why eBooks appear with or without covers depends on whether they are above or below the 1200 (approx) eBook level.

Other than that I don't have any problems other than the terribly slow response times for selecting library items, searching etc.

Have you looked at some of the threads where people discuss the images folder and it's contents?

Take a look for instance at https://www.mobileread.com/forums/sho...d.php?t=174388

I've found that on both the Kobo and the Sony that I own, the more books on the SD card, the longer the response times (as in, it takes forever to find a book and open it to read).
On my original Sony prs505, I had filled the ereader itself and an SD card with all the books in my library (over 1,500). Covers were all there but the reader was super-slow!
I therefore have changed my approach and only download from Calibre a few dozen books at a time, usually the ones I am most interested in at that moment and then once read, I delete them. Both the readers work like new (and as fast) when I do that. I can't speak to the cover issue on the Kobo because I have never put more than 50-60 books on it at a time.

Thanks for the link PeterT, hadn't seen that post. My problem was that I had hit the 7500 limit on the .Kobo\Images folder. I have just over 1300 books loaded. For every book cover Kobo creates five image files of various sizes. Plus there were around 1200 old image files from books that I never had installed on my KT. This put me well over the 7500 limit (why this limit exists I don't know). Following the suggestions from mconh in the link, I ran his .bat file which removes two of the five image files from each cover. I also deleted the spurious 1200 covers and my book covers now show up perfectly on my KT.
Thanks everyone for your help.
