When uploading a file to storage, is there a way to add a tag to the file?

I want to be able to add a tag of say "user X' to a file such that i can do a listfiles and only get the files with user X tag? I'm confused how to use permission to achieve this or do I just create different buckets?

TL;DR

There is a way to add a tag to a file when uploading it to storage. You can create a function that gets triggered on each file upload and update the collection with the necessary details, such as file ID and user ID. This will allow you to track each file and its associated information. If you want to add a tag to a file and filter files based on that tag, you can create a separate collection to store the details and update it after each upload. Using different buckets is not necessary for this purpose.

To keep tracking of your file the best workaround is to create collection that will have all the details, for example

file_id
user_id
... Then update it after each upload

I referring to files like a pdf. I thought they can only go in storage?

You always put the file inside a bucket using the storage module But if you want to track each file meta_data you will need to create an accompanied collection
