File Writer

The File Writer North Connector writes files and data to a specified output folder on disk. This connector is useful for local storage, data processing pipelines, or integration with file-based systems.

Specific Settings

Setting	Description
Output folder	Directory where files will be stored. Relative paths are resolved based on the Data folder (see About section).

File Naming Options

Setting	Description
Prefix filename	Text to prepend to the filename. Supports internal variables like @ConnectorName.
Suffix filename	Text to append to the filename (before the extension). Supports internal variables like @CurrentDate.

Dynamic Filenames

Use internal variables to create dynamic filenames:

• @ConnectorName: Inserts the name of the connector.
• @CurrentDate: Inserts the current timestamp in yyyy_MM_dd_HH_mm_ss_SSS format.

Example: With prefix @ConnectorName- and suffix -@CurrentDate, a file named example.file becomes: <ConnectorName>-example-<CurrentDate>.file

Best Practices

• Use absolute paths for the output folder to avoid ambiguity.
• Create a dedicated directory for each connector to keep files organized.
• Combine with transformers to:
  • Convert data to other formats (e.g., JSON, CSV).
  • Filter or enrich data before writing.
• Monitor disk space usage, especially when processing large volumes of data.
