Getting an error when browsing my books

[unabatedshagie]

I'm getting the following error when I'm using Calibre and I'm not sure if it's something I've done or not and if it is how I can fix it?

That's an error trying to read cover files from your calibre library. Unfortunately the error message comes from the windows kernel and so is not very useful. The first thing to do is run calibre without any plugins

calibre.exe --ignore-plugins

in a comamnd prompt

If that does not fix it, then try moving your calibre library to a simple lcaotion like C:\library or similar.

Still get the same error when loading with no plugins.

I've noticed that I've got a few books with no cover art showing and I get that error message when I click on them.

Not sure if three book files were corrupted, I've moved them out of my library folder, restarted Calibre and I can now click on the entries without the error showing. I'll just delete them from my library now that I know what's causing the issue.
