@file-type/cfbf

@file-type/cfbf

Detector plugin for file-type that identifies files based on the Compound File Binary Format, commonly known as CFBF or OLE Compound Document.

CFBF is a container format used by many legacy Microsoft Office files and other Windows applications. This plugin detects the container itself, not the specific document content inside it.

Installation

npm install @file-type/cfbf

Usage

The following example shows how add the CFBF detector to file-type.

import {FileTypeParser} from 'file-type';
import {detectCfbf} from '@file-type/cfbf';

const parser = new FileTypeParser({customDetectors: [detectCfbf]});
const fileType = await parser.fromFile('smaple.doc');
console.log(fileType);
