Hi Prosper,
If you are on Watson Studio Cloud, your notebook is running in a hosted non-persistent python environment.
So, the files you create will be written to the filesystem of that environment. You can list the files with a command such as `!ls -l`in a notebook cell.
Persistent storage in WS Cloud is managed through Cloud Object Storage (COS), and you have to explicitly copy the files from your local fs to COS.
Each project is associated to a storage area in COS, called a *bucket*.
When running in a notebook, you can use either direct COS API to write to that bucket, or use the `project_lib` helper library.
To do this, you need to:
1. generate a project token (from your project's Settings tab):
2. then insert the access code into your notebook (using the icon at the top):
4. When you switch back to your project's assets tab, you will find the newly created persistent file:
