The Library maintenace option in the Calibre Gui does not fix
the problem
I do not see any plugins in Calibre that fix this issue

I need to obtain or write some kind of script to test if the file in the Calibre metadata.db is found or not and return the the filename reported
from the metadata.db

then I can run a rename of the epub to match the filename reported
from the metadata.db

The other alternative is DOA ...

Running a large 5000+ ebooks Calibre library off a Flash drive is too slow!
I usually just open the ebook from the file manager when I read books
from the Flash drive

I also need to Calibre on Windows 7 because my Ubuntu Netbook
does not recognize the SDcard in my Nook Tablet and I do not wish to
eject the SDcard from the Nook each time I want to sync with Calibre

I actualy have all the epubs on the Nook...

Any help is apreciated!
TIA
Dave
