I have been writing a small Python app for several weeks. The application reads data from a Firebird database and it copies it to another DB. I\'m using FDB with Firebird embedd
You cannot access databases on a network share. Firebird explicitly disallows this*. However, as far as I can tell, the error you display simply means you're trying to use an invalid path to access file.
If you want to connect to a Firebird database over a network, you should connect to a Firebird server on the system hosting the database. That means running Firebird server, not using Firebird Embedded.
* : You can configure Firebird to allow opening database on a network drive, but it is a great way to corrupt a database if multiple processes try to modify the database from different hosts, it is something you really should not do.
