Hello @zagadepravinm,

You can try using Wait node

Here is a step-by-step guide to achieve this:

  1. Drag and Drop the Wait Node into your workflow.

  2. Configure the Wait Node:

  • In the configuration dialog, select “Wait for File” under the “Settings” tab.
  • Specify the file pattern you want to monitor.(Creation , Modification and Deletion)
  1. Execute the Workflow:

Thanks

@zagadepravinm ,

You can use the scheduler to automatically execute your workflow.

Hello @zagadepravinm ,

Correction to previous solution, the Wait Node by itself cannot help to re-execute the workflow.

As mentioned by @tqAkshay95 , you can use it in combination with scheduler for better results.

KNIME Server Scheduling:

  • Uses KNIME Server to schedule workflows to run at regular intervals. This approach allows you to automate the re-execution of nodes without manual intervention

Sorry for the confusion. Thanks
