Hi
I'm running 64 bit (v4.23) on Windows 10 Home laptop. Export got to about 75% then I got the error below. My backup folder has 14 parts (same number as the previous folder that I deleted although the part files sizes are smaller (I did delete a few books).
Can anyone interpret the error below and tell me how I can get a 100% export/backup please. Many thanks in advance.
Error:
calibre, version 4.23.0
