Editing external FileMaker data sources
A FileMaker data source stores the file paths that FileMaker Pro searches to access an external FileMaker file, table, script, or value list.
To add a FileMaker data source, see Connecting to data sources.
To edit a FileMaker data source:
1.
Choose File menu > Manage > External Data Sources.
The Manage External Data Sources dialog box appears.
2.
The Edit Data Source dialog box appears.
3.
File paths can be edited as text. Each FileMaker data source can consist of one or more file paths, separated by carriage returns. See Creating file paths.

FileMaker does not recommend using an asterisk (*) as a wild card character in network file paths as it slows FileMaker network traffic. When possible, replace an asterisk with the appropriate IP address.
 •
Variables are not supported in FileMaker data source references.
 •
Data source references are only to other FileMaker files or to ODBC DSNs. References to other files such as graphics are file paths.
