Sooooo, I may be trying to do something unconventional, but, here goes.
I have three different PCs; two desktops and one laptop.
- Desktop #1 is my main machine, holds the majority of my books and has files backed up to Mega. To answer your question, it's the home machine I started with.
- Desktop #2 is the one I use the majority of the time, which ends up with some new books on it. This is a new machine that I use most of the time in the office.
- The laptop is for casual browsing in the evening and occasionally gets some new books.
I have used 'Save To Disk' to save books from #2 or the laptop to a Thumb-drive, which are then imported them into #1. So far, so good.
I have also 'backed up' all my books from #1 onto a thumb-drive.
What happens when I save from different machines to my 'Calibre Thumb Drive' or, maybe more to the point, if I backup my files on Day 1 using Save To Disk and then use it again, to the same disk, several days later?
Also, while I have the floor, in going through folders on my 'Calibre Thumb Drive', I find empty folders, they may have a named sub-folder, which is empty.
Thanks for any help!
