Thanks, but when prompted for a path, I keep getting an error about the syntax.

> calibre-debug --export-all-calibre-data
Enter path to an empty folder (all exported data will be saved inside it): c:\test

I tried different variations, c:/test, "c:\test" etc but no luck.

Python function terminated unexpectedly
