@Teodor May I ask you to provide you some more information (screenshots) how to restrict/protect downloading files directly by typing full URL path to files?
Server model: NodeJS
I have folder /public/export and I want so that downloading files from this folder would be possible only via Server Connect - File download action, not by typing URL path.
Just don’t put the files in the public folder 
When they are outside the public folder, they can’t be accessed by a direct link.
Can you please show me the exact location in your project folder (files view in Wappler)?
Here you go:
But how do you test your server action? How do you run it?
I have an anchor button which executes Server Connect action configured via routes.
I just added additional file download step with new path (pointing to root/export) and disabled working one (which points to public folder).
can you post your button code please, as well as a screenshot your route config?
@Teodor let me guess, you’re not using Docker
@Notum let me guess, you’re using Docker
Folder export (/export/) is not exposed inside Docker container, as checked on docker-compose.yml of Development environment
Anchor button:
Route:
Your screenshot shows test/test server action while your route and code point to another one
Which is your server action exactly what are its steps?
No, i am not using docker.
@Notum follow the steps in this post:
This will allow you to expose your “export” folder into your Docker container.
The more appropriate approach is to expose a more generic folder “storage”, which inside you put the “export” folder, so it comes:
/storage/export/
Also a note for newbies using Linux, the initial slash (/) is specific to Wappler, it refers to the app’s directory, not to the actual filesystem / in Unix/Linux
