Properly handling CRUD for local and remote files in a drag and drop file upload component

I'm trying to build a CRUD interface for a drag and drop file upload component that allows users to manage remote files, and also upload new ones. However, I'm having difficulty because local and remote files are fundamentally different and I'm struggling to find a clean solution. For example acceptedFiles are meaningless for files that are already to remote.

Is this a common issue when building file upload components and is there a standard way to handle it?

For example, when I try to add a local file to the group, this is the result [Screenshot 2].
