File should be attached and not be uploaded on wordpress, in the gravity form

Can we attached the file without uploading it to WordPress and send it to the 3rd party (Sharefile).

Hello Kanhaiya. When using the Gravity Forms file upload fields, the files will always be uploaded to your server first.

However, if it isn’t a privacy/security concern that the file spends “some amount of time” on your WP website, either a coded solution with gform_after_submission or use of the Gravity Flow Form Connector extension to update fields to remove the attachment could be an effective way to address the issue.
