This is a simple XPages application to share files with others without using any login or user management. The access to the downloads is filtered by a customer ID only. You can provide the ID to your customer so he can see his downloads only. In addition you can provide readers and authors fields to restrict internal Notes users when they are logged in.
With release 2.0.0 this application uses Bootstrap4XPages plugin and the OpenNTF Domino API.
