to assign uploadfolder / usernamefolder / img

[ingnrcs]

Hello, I wonder if there is a clear method or example of how to assign a directory to each user of my web platform.

I have tried to search and I have seen many examples, but none clear or updated that is functional.

so they can understand me a little better.

I wish:

https://mysite.com/upload_folder/username_folder/img.jpg

and NOT a generic route like

https://mysite.com/upload_folder/img.jpg

Thanks in advance
