Managing files uploaded by users

Hello,
I am building an app that includes some forms, these form contain file upload options.
My concern is how I will be able to manage my storage, can I delete some files uploaded by the users of my app?

Thanks

I am switching to a Postgres data source and am trying to think about the architecture when a file is uploaded, and how it would all work given Postgres does not store files.

@jafarhajeer what is your datasource? That usually handles the storage.
