如何使用 Node.js 制作应用程序，它可以分隔所有具有相同扩展名的文件？

Question

How to write code in node.JS in which we select a directory and the code automatically separates all the files of that selected directory with the same extension and put then in a separate folder.

Answer 1

Something like this will work. Using fs module and path module

Which will first check the extension and rename file (move) to new folder.

You can make changes accordingly. Use if

const testFolder = './';
const fs = require('fs');
var path = require('path')

var oldPath = 'old/path/file.txt'
var newPath = 'new/path/file.txt'

fs.readdir(testFolder, (err, files) => {
    files.forEach(file => {
        const ext = path.extname(file);
        fs.rename(oldPath, newPath, function (err) {
            if (err) throw err
            console.log('Successfully renamed - AKA moved!')
        })
    });
});
