I want to upload file 2GB.
I changed middleware.js in config like this

module.exports = {
  settings: {
    parser: {
      enabled: true,
      multipart: true,
      formidable: {
        maxFileSize: 20 * 1024 * 1024 * 1024,
      }
    }
  },
};

When upload I have error The file is too big. What causes this problem? I followed Strapi documentation to change maxFilesize.
