Calibre can't access files in Kindle memory

[Shanekom]

Hallo

I've gone through the previous posts about this problem but haven't been able to find a solution. I've been downloading books to my Kindle for months, and suddenly this morning it just gives the message below. I didn't do anything to either the Kindle or upgrade the Calibre. My computer displays the Kindle documents, there's just one device attached to the computer, I plugged in the USB at the back, restarted, rebooted, nothing helps. I'm completely lost where computers are concerned and would appreciate it if someone could take me by the hand and help me.

Thanks
Susan

Your kindle's drive's root is full. Open windows explorer go to G:\ and delete all the files and folders you see (I assume you have the books that are in your kindle already in calibre), if not back them up first.

Unfortunately this didn't do anything except remove all the books from my Kindle. They're still available on Calibre - but how do I upload it to my Kindle. It still gives the message:

Reformat G: as FAT32.
