Schijnbaar kwam dit in 2015 al voor en kwam iemand in 2018 met een oplossing.
Want schijnbaar heeft het met het synchroniseren van boeken te maken.
A fix: I've had similar problems the past few days (more than 2 years after the original post above). Below is what I did to fix it (it might be overly complicated, I'm not sure which of the following are the key steps). Go to "Adobe Digital Editions" -> Preferences, and turn off "Automatically download your synced books to this device". Then I was able to delete two books form the ADE (Adobe Digital Editions) Library window. However there were two new unlabelled books added (I don't remember exactly what they were called). These corresponded to two *.acsm files had been added to ~/Documents/Digital Editions/CloudSync. Back in the ADE Library window, I clicked on these unlabelled new books, and this caused ADE to download the books I thought I had deleted again, and the two *.acsm files disappeared. I then deleted these two books again. I then deleted the corresponding epub files from ~/Documents/Digital Editions. I then went to "Adobe Digital Editions" -> Preferences, and turned back on "Automatically download your synced books to this device". The two books stayed deleted.
(I'm running ADE 4.5.7.179634 on a Mac. The above instructions might need to be adjusted some for a Windows computer.)
Deze oplossing komt uit 2019, toen was het problemen in Adobe er nog.
I have found something that appears to work. Go into File Explorer then to the My Digital Editions folder. Go through all the subfolders and delete all the Cloudsync subfolders (there are four: You will find Cloudsync under My Digital Editions, then three others: Under Annotations, Manifest, and Thumbnails). After I deleted these four Cloudsync subfolders I found that Adobe Digital Editions program worked fine and I no longer have books showing up in my Library that I did not put there. I also check to see that any books I delete from my Library are no longer in any of the subfolders under the My Digital Editions folder. If you accidently delete a subfolder that prevents Adobe Digital Editions from working properly, remove and reinstall Adobe Digital Editions and start over.
I have files that I have erased repeatedly but they keep reappearing when ADE syncs with Cloud Sync. I have disabled the Sync function in Preferences and I have even manually deleted the CloudSync folder in Docs/My Digital Editions but those files just keep popping up! How do I access my files...
