Amazon Cover Bug Folder Not Populating
I am running Calibre 5.44, 64-bit on a 64-bit Win 10 PC. I have 9K+ books on my Kindle Oasis. However, at this point the files are very hit and miss (more miss) when it comes to covers transferring. I am aware of the Calibre cover rebuild feature, which utilizes the Cover Bug folder. However, I am seeing something very strange.
When I upload to the Oasis, I also keep the File Explorer open to the Cover Bug folder on my Kindle where I can see if a file was sent and has a corresponding thumbnail created as well. I did not do this for the first 9K books, but only when I began having the issue. I can sometimes transfer 1 book at a time and see the cover populate, and when I eject the Kindle I see the book pop up in the library as intended, begin indexing, etc. Most times, I do the same transfer of the same file format (AZW3) and a file is not created in the Cover Bug folder. Once metadata transfers and I eject the Kindle, the cover predictably does NOT show up in my library. The indexing and file work as intended. Does anyone know why select files may NOT be transferring cover files? I am changing settings on one book at a time, but have spent a huge amount of time with no results. Any help is appreciated! Thank you. |

right click preferences button, choose restart in debug mode, post the debug log after transferring a file for which the cover doesnt transfer.

There you go: PermissionError: [Errno 13] Permission denied: 'E:\\system\\thumbnails\\thumbnail_e8d40faf-0d1d-48ac-90ee-112b4716a7cc_EBOK_portrait.jpg'
Its permission denied error check the permissions on the cover bug folder. See https://manual.calibre-ebook.com/faq...n-denied-error for all the possible reasons. |

Thank you Kovid, I am looking into this. I am unable to see the System folder in my File Explorer, even with Show Hidden Folders enabled. I am assuming I will need to see this folder before I can edit permissions on it.

Okay, I FINALLY figured this out. The reason this was not working was due to Google Drive backing up my Calibre Library folder, and when Drive accessed the files, some would through and permissions error and some wouldn't, allowing SOME covers to be copied to the Amazon Cover Bug folder.
The Calibre book files were being routed to a standard library folder in my documents folder called "Calibre Library." However, I recently selected that folder as one of the folders for Google Drive desktop app to scan and upload. This background usage/scanning of the folder threw permissions errors and resulted in very sporadic behavior. Another clue was that when deleting books from my library via the Calibre app, the app would sometimes throw an error that the file was in use by another program, although I had no knowledge of Google Drive performing a scan. I paused all syncing and removed the Calibre Library folder from the backup options in Drive, and afterwards everything worked perfectly. The sporadic behavior initially made me look for differences in the book files themselves, then explore permissions issues before FINALLY noticing today that the Cablibre Library folder has recently been added to the backup schedule. Don't make the mistake I did everyone- backup and then turn off automatic syncing! Thank you Kovid, it was your advice about debug mode that finally lead me down the right path! ![]() |
