Copy and paste

I want to copy and paste all the books on the Kobo to a folder on Windows.

I'll sort it out there. The Glo is too slow to do anything with.

Problem is that Calibre says I have 185 books and Kobo twice that. Since the counts don't match, something's missing from somewhere.

I tried exporting to a folder, made up a name for the folder I didn't even have on the computer (a rarely used obscenity) and was told the folder was in use!
Edited the whole path every which way and Calibre still said the same.

How do you get everything transferred in one fell swoop?

I'm getting ready to give Kobo the gate and delete my account.

Thanks
