Is "Files" field not available in Kirby 2.4?

When using type: files in my blueprint, for example:

label: Downloads
type: files

The page returns the following error/exception:

The files field is missing. Please add it to your installed fields or remove it from your blueprint.

Note: I’m unable to upgrade Kirby at the moment, so any solution to this for 2.4 would be much appreciated.

There is no files field in Kirby 2. These are the available field types:

Alternatives to the built-in fields are plugins like a multiselect field or the images field.
