Also known as WA002.

Distinct from OE004, and FL003.

Acoustic sensors can generate null files. These are files that have a length and a size, but are filled only with zeroes.

This problem is distinct from empty files, small files, short files, or corrupt files.

Null files can be hard to associate with a manufacturer, because they have no internal metadata, hence why we have a catch all problem identifier.
