Yeah, tell me about it.

And my usage essentially hasn't changed, from the first 18 months, where I had no real issue, until now. What has changed, is updates to my device, so clearly they screwed something or the number of ebooks on my device is a factor ... though to be sure, my Kobo device still has much more space free than used.

And as usual, I always treat my devices and drives well, which is carefully. I also never charge my devices, until almost flat ... be that ereader or phone or tablet etc. I eject properly, store and transport properly, etc etc.

My money is on nerdy coders and flawed management as being the real issue ... and I've seen that across many devices.

Latest v1.9 update now available, see the first post.

This involves several changes and improvements since my last (v1.4) update upload.
I've held off until I've done a reasonable amount of testing, especially with the new CLONE approach.

[Tuesday 6th May 2025] (v1.5)

Spoiler

As designated previously, the ADD button has two states, ADD or COPY. The related checkbox that picks which state is active, now has a third state (block instead of a tick). So what was previously a copy routine involving a CLONE setup, has now been moved to the third (block) state choice. The new second (tick or checked) state, is for copying one or more images from the BACKUP IMAGES folder, to your Kobo device. NOTE - This is a possible recovery (copy back) solution, but only if you have indeed used the BACKUP IMAGES button previously, and one or more images exists in that folder for the selected ebook, that is currently missing one or more images.

[Monday 21st July 2025] (v1.6)

Spoiler

The LOG button now presents some choices. One choice is to present the 'Log.txt' file as previously. The other two (new) choices involve extracting and viewing extracted portions of the Log file. NOTE - Basically a sorted list of ebooks with covers that were fixed, is saved to a text file for viewing. This is the best way to see if covers for specific ebooks, have needed to be fixed more than once.

[Wednesday 23rd July 2025] (v1.7)

Spoiler

The CLONE button now features a changed and simplified clone process. You basically get two choices, Clone or Restore. It is now all about backing up the ebook image folders & files to a clone folder on your PC, and then quickly restoring from that at need. This potentially reduces the number of cover images to be fixed, to just those involving more recent ebook purchases. It should save time and effort. Added an 'Open Clone Folder' button to the 'Program Settings' window.

[Friday 15th August 2025] (v1.8)

Spoiler

The CLONE button processes of 'Clone' and 'Restore' now show a splash. The visual check window for clone images now makes it clearer where the source and destination images are located. The CREATE button query dialog for replacing possible existing images, is a little clearer about that. The 'restart' option is now properly cleared after a program restart. Some splash screens now give better feedback.

[Tuesday 26th August 2025] (v1.9)

Spoiler

Added another right-click option to the dropbox - Open the device drive folder. NOTE - This might be handy after doing a 'Restore' clone process and restarting the program, where perhaps you forgot to open the device drive folder before that. Added more feedback when cloning or restoring images, in regard to number of entries & images checked. NOTE - Entries is essentially the number of images divided by three ... remembering that the number of entries (or ebooks) listed in the 'KoboReader.sqlite' file is not the same as the number of ebooks downloaded to your Kobo device, as it also contains advertised ones.

Latest v2.4 update now available, see the first post.

This involves several changes and improvements since my last (v1.9) update upload.
I've held off while I've done more testing, and kept adding and changing things. That said, testing has been minimal with some elements, so no guarantees.
A few new screenshots are included in applicable spoiler sections.

Of particular interest for users, is an additional fairly comprehensive 'Instructions.txt' file, which should be very helpful and informative.

[Tuesday 2nd September 2025] (v2.0)

Spoiler

Very minor update, which adds slightly more feedback (counter) when checking for device images, and an additional dialog to say when the full process is complete.

[Wednesday 8th October 2025] (v2.1)

Spoiler

Improvements made to the Clone and Restore processes, such that you can now do 'Replace ALL' and ABORT all, with a newly added KEEP button that can also be an ABORT button, due to the 'Keep ALL' checkbox being a three state one.

[Monday 27th October 2025] (v2.2)

Spoiler

Added clone preview options for 'Image File' and 'Cover Image', that only work if the 'Clone Images Folder' and applicable files exist. The 'Compare Cover Images' window will now abort if the 'X' is clicked, rather than continue to loop through remaining image files. Added a new right-click option for the 'Ebooks List' called 'Enable CLONE COMPARE'. This renames the 'Find Kobo Device' button to 'CLONE COMPARE', which can be used to view all 'Clone Images Folder' image files (those that have a list entry), which can then be replaced, if desired, using the REPLACE button. It can also be used with the right-click 'Enable NEXT For Imported' option to just step through image files for imported (side-loaded) ebooks. Bugfix for some variables not declared.

     

[Tuesday 28th October 2025] (v2.3)

Spoiler

The 'View the missing sub-folders list' button now presents a 'Sort Query' and process. Renamed the EMPTY FOLDERS button to REMOVE ADVERT IMAGES, and removed the EMPTY FOLDERS process. Relocated (swapped) the CLONE and MISSING IMAGES buttons. Renamed the MISSING IMAGES button to just MISSING and renamed its group to 'Images List'. Added a process to the REMOVE ADVERT IMAGES button, that obtains a list of image file names for all entries on the 'Ebooks List', and then uses that to remove any image files found in the 'Clone Image Folders' that aren't on that list, which are typically either advert ebook images and perhaps cover images for ebook files not yet found on the Kobo device. That process should significantly reduce the number of image files to be used in the clone 'Restore' process. ADVICE - 'Clone' and 'Restore' should only be run in a specific order, if extracting new entries to the 'Ebooks List', else newly added ebooks on the Kobo device could lose their cover image files in the 'Clone Image Folders'. The best approach now, would be to (1) use the clone 'Restore' option first, followed by (2) updating the 'Ebooks List' entries using an updated 'KoboReader.sqlite' file, then (3) fix (Determine, Create, ADD) cover images that are missing etc, then (4) use the 'Clone' option, followed by (5) the REMOVE ADVERT IMAGES button process. Or you could do that last process (5) just before the next update & fix.

[Wednesday 29th October 2025] (v2.4)

Spoiler

The 'Kobo Device' group has been renamed to 'Clone Options', to be more relevant to latest program changes. The dropbox has been improved, and provides access via a right-click USAGE INSTRUCTIONS menu option, to a newly provided and fairly comprehensive 'Instructions.txt' file, which can also be accessed via the 'Program Information' dialog button on the main program window. This new 'Instructions.txt' file covers the basics of most usage, providing some information as well as the order of steps to take, and what they involve. NOTE - Some redundant elements have also been dealt with, but perhaps not entirely. So while the program does offer other features, sticking to the new instructions is probably best. That said, this 'Latest New Features.txt' file, does provide some insight into features outside the basic instructions, but only via older program versions information, which could now be redundant, so be aware of that possibility. This update includes a bugfix for the right-click Dropbox menu option, View the Folders List, which wasn't working (not finished).
