I have a Ubuntu 20.04/Windows 10 dual-boot configuration and was able to successfully share Firefox/Thunderbird profiles between those partitions. I was wondering if something similar is possible for the Calibre library but I could not find any helpful instructions in the internet. So far, my Calibre library is in the Linux partition. I assume that one has to generate it first in Windows and then point the Linux version of Calibre to this library. But how?
