It's not possible to do that using railway-provided tools since there are none of those, you'd have to write some code that can do that for you, there might be a template that you can use to manage your volume files too

Thanks, just found the template "Filebrowser data" to interact with a volume.
Is it possible to attach the same volume to multiple services ?
This way, I can interact with my volume via the Filebrowser, and my app will write in it independently.
Thanks!

It is theoretically possible - and very easy, but I'm not sure if Railway has that functionality built-in
