The File exists step verifies the existence of a file by checking filenames coming from previous steps, and adds a Boolean flag field to the input fields of the output.
The following fields are available to this transformation step:
| Field | Description |
|---|---|
| Step name | Specify the unique name of the File exists transformation step on the canvas. You can customize the name or leave it as the default. |
| Filename field | Specify the input field that will contain the filename at runtime. |
| Result fieldname | Specify the name of the field that will contain the Boolean (Y/N) flag. |
| Add filename to | Select to add the filename to the list of filenames that can be used in the next job entry. |
| Include file type | Select to include the file type in the field. |
| File type field | Specify the name of the field that contains the file type as a String (for example, file, folder, or imaginary). |
