Database Path (ODBC Connections)

The database path for ODBC is c:\inetpub\vhosts\domain.com\ or d:\inetpub\vhosts\domain.com\ where, domain.com is your domain.

You need to add the actual directory name to that path. There is also a private\ directory that you can use as well. In addition you can create directory in your webroot - httpdocs\ and then password protect it from Plesk.
