Docx content type recognition

[nektarios-workable]

Hi, I'm using mimemagic to recognise the mimetype of files and in case of docx files what is returned as type in some cases is application/zip. I found here the suggestion to put the following: MimeMagic.add('application/vnd.openxmlformats-officedocument.wordprocessingml.document', magic: [[0..2000, 'word/']]) in the config/initializers/mime_types.rb file. The thing is, can someone explain what is this magic: [[0..2000, 'word/']] magic specification? What does it mean? What is it doing?
