I am using a FileMaker file with spaces in the name and AutoSender gives an error

When using AutoSender with xDBC to connect to FileMaker, the standard rules apply that are described in FileMaker's ODBC/JDBC Guide:

If your database name contains spaces, replace them with the escape characters %20. For example, if the database name is "MY DATABASE", use "MY%20DATABASE". Double-byte characters are not supported.
