Append to File

Append to File

Type: append-file  ·  Package: Filesystem Activities v1.0.0  ·  Output: string

Adds text to the end of a file, without deleting what you already have. If the file does not exist, it creates it. It is the ideal activity to build logs or accumulate lines throughout an execution (or several).

How it works

Add the content to the end of the path file. By default it prepends a line break (newLine = true), so that each call is on its own line.

Required parameters

Parameter	Editor	Description
path	expression	File path.
content	expression	The text to add.

Optional parameters

Parameter	Editor	Description
encoding	text	File encoding. By default "utf-8".
newLine	boolean	Add a line break before the content. By default true.

Output

Returns the path of the file, in case you want to capture it into an output variable.

Example

Record each processed element in a log file:

For Each   items = = facturas   itemVariable = factura
 └─ activities:
      ... procesar ...
      Append to File   path = "C:/logs/procesadas.txt"   content = = factura.numero + " — OK"

Append vs Write

• Append to File: Add to the end, keep the previous. For logs and history.
• Write File: Replaces all content. To generate a file from scratch.

Related activities

• Read File — read the accumulated content.
