How to update where the files are stored in Django app

I have a Django app that contains multiple models with FileField. I am saving by default every file directly in the Media folder. But as the app grew larger also Media folder became bigger. Now my idea is to move the files into separate folders split by models. So I am wondering what is the best practice when it comes to this? Shall I move the files to separate folders, then manually update every file location in the Database and then update Filefield path for every model? Or is there better approach?
