Calibre on Win 8.1 Desktop not working with Onedrive online-only files?

[robcohen]

Having some difficulty after moving my library to Onedrive on a different machine. Keep getting this message, sometimes whenever I click on a book:
calibre, version 2.13.0
ERROR: Unhandled exception: <b>Exception</b>:Failed to open u'C:\\Users\\Robert\\OneDrive\\OneDrive Documents\\Calibre Library\\Philip Hensher\\The Northern Clemency (7412)\\cover.jpg' with error: [Errno 22] Invalid argument

This is only true on the other PC, not the one where I originally moved the files to OneDrive. Difference I noted is original machine has the files in OneDrive marked as Available offline and the second machine shows them all as Online-only.

Is the problem here with Calibre interfacing with OneDrive. Realize a solution is to just change the files on the 2nd machine to Available offline (haven't tried that yet). Or is this a bug in OneDrive?

Thanks!

@robcohen - you need to read this ==>> I am getting errors with my calibre library on a networked drive/NAS?

The bottom line is if you run calibre over a 'network' it wont work reliably, services like OneDrive, DropBox, Copy.com etc provide a 'network'

The solution is simple stop the cloudservice before you start calibre and restart it when you're done with calibre - but don't run calibre and any of the cloud service at the same time. And be especially careful with GDrive - there's a sticky at the top of this sub forum

I have calibre working this way with Windows 8.1 on a couple of libraries
