IOError: [Errno 22] Invalid argument

[TomSpot]

Recently I've relocated my Calibre database and after that I've updated to 3.28. Every title I select leads to IOError: [Errno 22] Invalid argument .

Can anyone support me on this error?

Thanks!!

Relocated your database to where? That error typically happens if you have oved your calibre library to some location such that the path is too long for windows or the path contains unicode characters that aren't representable in the default codepage, etc. Move your calibre library to a simple folder such as c:\library and you should be fine.

Thank you very much for replying. I just found the mistake.

I've relocated Calibre's database to a OneDrive location. However I forgot to permit OneDrive to start-up on Windows startup. So any Calibre data change led to the error.

You might want to relocate it back to your computer. Calibre and cloud storage are not happy campers.

I have seen various warnings about Calibre and cloud storage before, and I sure there is something to them...but I have successfully kept my Calibre library in Dropbox for many years now. I only run Calibre when I need to add new books, and it is generally not running when I access the Dropbox location from other devices. So in my experience cloud storage is doable, and it means I can access my books remotely (without having to have an always-on Calibre host); but do it at your own risk.

Sounds as if you are trying to avoid the conflicts that seem to be the cause of issues when using calibre and cloud storage. As you said, do it at your own risk when it is so tempting to start accessing your library using calibre on another computer.
