Tips and Advanced usage

This node is designed to be used in process that reads data from a folder where new files appear daily.

If using Number of files option, make sure that there is a node at the end of the process that moves the files in a different folder (DONE/ERROR for example). This can be done using Folder Mover .

  "takeFiles": 10,
  "dateFilter": {
    "Field": null,
    "Operator": null,
    "Unit": null,
    "Criteria": "0"
  }
}

Example 2

This example reads all the files that were modified in the last day inside C:\InputFiles folder.

{
