/ File Formats
File Access with the file: Protocol
DuckDB supports using the file: protocol. It currently supports the following formats:
file:/some/path(host omitted completely)file:///some/path(empty host)file://localhost/some/path(localhostas host)
Note that the following formats are not supported because they are non-standard:
file:some/relative/path(relative path)file://some/path(double-slash path)
Additionally, the file: protocol currently does not support remote (non-localhost) hosts.
