I have multiple calibre libraries stored on a network share. To improve performance on Windows 7, I want to use the CALIBRE_OVERRIDE_DATABASE_PATH environment variable to store the metadata.db files for each remote library in a local dir.
In 2009, itimpi showed how to use this setting for a single library.
I'm wondering if there's a way to modify itimpi's batch file to provide different metadata.db paths for each library. I'm not sure how the script works, so I don't know where to start. Also, I should note that I use the portable version of calibre - would this work with the portable version?
