[Borewit]

Following Microsoft documents are not tested as .msi (Windows Installer) or [MS-CFB]: Compound File Binary File Format:

file-type/test.js

Lines 178 to 182 in 4a4d39c

	msi: [
	'fixture-ppt',
	'fixture-doc',
	'fixture-xls'
	]

const FileType = require('file-type');
const path = require('path');

(async () => {
  const fileType = await FileType.fromFile(path.join('fixture', 'fixture-xls.msi'));
  console.log(fileType);
})();

Outputs:

Ah, these files used to be false positives, but are no longer tested as false positives. It is not something like a known issue (known false positives).

The fix 702f795, to prevent false positives, seems to be more luck than wisdom, as it only narrows down to a specific version number of [MS-CFB]: Compound File Binary File Format:.
