# ConvertDocumentFile

Knowledge Discovery documents can have one or more associated files. In NiFi Ingest, FlowFiles that represent documents can contain:

- a path to a file stored on a local or network file system (a `contentfilename` part)
- embedded binary content (a `contentfile` part)
- a reference to a file stored by an external storage provider such as Amazon S3, Azure Blob Storage, or Google Cloud Storage (an `externalfile` part)

This processor provides a way to convert between these types of FlowFile part. For example, the processor can take embedded binary content, upload the file to external storage, and replace the `contentfile` part with an `externalfile` part.

For more information about document FlowFiles, see Introduction to FlowFiles and Documents.

## Properties

Name | Default Value | Description
--- | --- | ---
Convert Source Type | all-source-types | The type of associated file to convert from. For example: When you select filename, FlowFile parts containing local file paths are converted, but the processor does not modify FlowFile parts containing embedded binary content.
Convert Target Type | embedded-file | The type of associated file to convert to: filename embedded-file external-file NOTE: Reading files from external storage can be much slower than reading local files. Using external storage could degrade performance, especially if your dataflow has a series of processors that all require access to the files.
Idol Flow File Service |  | When you convert associated files to external files you must specify an IdolFlowFileServiceImpl that manages the connection to the external file storage provider.
Delete file if have ownership | True | Whether to delete the original files, when converting from file names or external files to another type of associated file, and NiFi Ingest has ownership of the original file.

## Relationships
