I backup my Calibre files, but evidently that was NOT enough. I now know I needed to EXPORT them!
Windows 10 update required a clean install. So now I have two backups (mine and my husband's) of our Calibre books and the latest version of Calibre but can't get those backed up files into this newest version.
Anyone have any suggestions, besides, "Oh, well, now you know--export!"???? Maybe I'm not holding my tongue correctly!?!?
Thank you any assistance.
