Electron附带了Node.js，它具有强大的文件系统API，您可以使用文件管理器的所有功能。
我写了几个函数来帮助你开始：

• getDirItemInfo()函数的作用是：为指定路径创建数据对象
• getDirItems()函数获取目录的内容，并为每个项目创建一个数据对象。

const _path = require('path')
const fs = require('fs')

async function getDirItemInfo (path) {
  const basePath = _path.parse(path).base
  return await fetchItemObject(path, basePath)
}

async function getDirItems (dirPath) {
  return new Promise((resolve, reject) => {
    // Read directory and get items
    fs.promises.readdir(dirPath)
      .then(basePaths => {
        const statsPromises = basePaths.map(basePath => {
          const path = _path.join(dirPath, basePath)
          return fetchItemObject(path, basePath)
        })
        return Promise.all(statsPromises)
      })
      .then(contents => {
        // Remove items that couldn't be accessed (undefined, null, false) 
        contents = contents
          .filter(Boolean)
        resolve(contents)
      })
      .catch((error) => {
        console.log(error)
      })
  })
}

async function fetchItemObject (path, basePath) {
  try {
    let dirItemCount = null
    const stat = await fs.promises.lstat(path)
    const name = basePath === '' ? path : basePath

    if (stat.isDirectory()) {
      // Count dir items and ignore dirs that couldn't be accessed by readdir
      try {
        const dirItems = await fs.promises.readdir(path)
        dirItemCount = dirItems.length
      }
      catch (error) { 
        console.log(error)
      }
      stat.size = null
    } 

    return ({
      dirItemCount,
      name,
      path,
      stat
    })
  } 
  catch (error) { console.log(error) }
}

// USE FUNCTIONS:
let path1 = _path.normalize('E:/test/test.jpg')
let path2 = _path.normalize('E:/test')

fetchItemObject(path1)
  .then((result) => {
    console.log(result)
  })

getDirItems(path2)
  .then((result) => {
    console.log(result)
  })
