## Messages flow ### Input Only the files to be used in this component must be in the current pipeline directory. ### Output ``` { "fileName": "pipeline-example", "success": true } ``` * **fileName:** name of the final file. * **success:** when the call is successful. ## Append Files in Action See below how the component behaves in a determined situation and what its respective configuration is. ### Appending multiple files * **File Name:** final\_file\_final.txt * **Charset:** "UTF-8" * **Custom Append Files Specification:** enabled * **Files to Append:** ``` [ {"fileName": "file1.txt", "charset": "UTF-8"}, {"fileName": "file2.txt", "charset": "UTF-8"} ] ``` * **Fail On Error:** false * **File content:** final\_file.txt ``` HEADER line1 ``` * **File content:** file1.txt ``` file1 test ``` * **File content:** file2.txt ``` file2 another test ``` ### Output ``` { "fileName": "final_file.txt", "success": true } ``` * **Final file content:** final\_file.txt ``` HEADER line1file1 testfile2 another test ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
