This app checks whether a folder exists at a specified path, which can be built dynamically using variables. Depending on the result, jobs are routed to the success or error connection, so your flow can react before further processing takes place.
With the "Invert logic" option, the check can be reversed: the job succeeds when the folder does not exist. This is useful for detecting duplicates, for example to verify that an order or customer folder has not been created yet.
Typical use cases include verifying that directories or mounted network volumes are available, validating dynamically constructed paths, and preventing jobs from overwriting existing data.
