Mixing of Loading Methods

HarryO53 · 02-18-2011, 10:13 AM

I was wondering if mixing of loading my Nook between Calibre transfer and direct to card transfer from my iMac will screw up Calibre's library?

I was going to take an already 'Calibre loaded' microSD card and move more content to it using my iMac's card reader.

Will this mess Calibre's accounting of things up? Does Calibre use pointer files to keep track of what's on the card and what's not?

Thanks in advance!

That should work- I've done it once or twice. Calibre might take some time to rebuild its metadata cache the next time you connect the device, but apart from that, nothing should happen.

There is a file calibre puts on the device called something like .calibre.metadata. When you connect he device to calibre it looks at the books listed in it. If they've changed or if it finds books on the device not referenced by the file it updates the file.

There is no danger in mixing using calibfe and manually copying files to the device. These situations are accounted for.

Thanks gents! I had tons of trouble just getting the Nook to list contents properly when I first got it. Was manually loading then. Wanted to make sure before I screwed things up again. Sure different than an iOS device!
