Introduction
The To File component is a destination component that writes incoming data to a file or multiple files as needed. It serves to expand on the File Writer component with additional configurations and settings.
This adapter can be easily modified to add additional functionality or to fulfil extra requirements.
Running the Component
The below steps assume the correct user permissions are in place to read/write files.
Using the button, import the To File component.
Fields marked with an asterisk* are required, otherwise default values defined in config.json are used:
Field | Description | Default Value |
|---|---|---|
DestinationDirectory * | The directory where the output file(s) will be stored. The adapter will attempt to create it if it does not exist. | - |
OutputFileMask | The name and extension of the output files. See Additional details. |
|
OneFilePerMessage | Specifies whether each inbound message will have its own file. |
|
OutputEncoding | The encoding used in the output file. If left blank, encoding will be updated to the default according to OS. See supported encodings in Additional Details. |
|
Escape8BitCharacters | Specifies whether to escape non-ASCII characters in outbound messages. Ex. "é" would be sent as "\XE9\" (in Latin-1 or Windows-1252) or "\XC3\\XA9\" (in UTF-8). |
|
UseTempFiles | Specifies whether to use temporary files while writing. When true, it will append “.tmp” to files currently being written until the component is done writing to them. It will only remove the .tmp extension when a new file is written in. |

Example Configurations
If you want one file for all messages:
Set OneFilePerMessage to false
This will result in a single “output.txt“ file containing all messages.
The OutputFileMask will behave differently depending if OneFilePerMessage is set to true:
OneFilePerMessage set to false will result in a single file “output.txt“ that all the incoming data will be written to.
OneFilePerMessage set to true will result in individual files generated as output.txt, output(1).txt, output(2).txt and so on. Similarly, with a timestamp mask “output_%Y_%m_%d_%H_%M_%S.txt”, if two messages come in at the same time then the name of the files will be: “output_2024_12_30_16_45_55.txt” and “output_2024_12_30_16_45_55(1).txt”
If you want one file for every message:
Set OnFilePerMessage to true
Using the default OutputFileMask, the timestamp will be updated with the current time, each time a message is written to the file.
If you want one file for all the messages that came in the same second/minute/hour/day/month/year:
Set OneFilePerMessage to false
Messages will be written to files according to the OutputFileMask timestamp specified.
If 2 bits of data arrived at 2024/12/30 at 16:45:55, they will be written to the same file with the name “output_2024_12_30_16_45_55.txt” (unless the OneFilePerMessage field is set to true).
If another bit came a second later, it will create a new file “output_2024_12_30_16_45_56.txt” and so on.
