FileEntity

const {FileEntity} = require('../index');

const tempPath = FileEntity.pathJoin(__dirname, './temp');

const fileEntity = FileEntity.of(tempPath);
console.log(fileEntity)
const tempFile = fileEntity.createFile('temp.txt', 'test');
console.log(tempFile)
tempFile.rename('temp2.txt');
console.log(tempFile)
tempFile.remove();

控制台输出
