directory tree, and list of files in PyQt5

Need to insert a directory tree, and a list of files, in the application on PyQt5, I did not find it in the documentation.

Maybe someone knows how to relize(screenshots below)

ftp = ftplib.FTP('192.168.0.1', 'Artem', '1204')

I don't have some of the modules you're working with, so I've commented something out. Uncomment the lines marked # #@

I don't see the overall design of your app, so insert

self.grid.addWidget(self.tree, ...)

Where you need it.

import sys
import ftplib
#@ import easygui                                                         # #@

from PyQt5 import QtCore, QtGui, QtWidgets                                # +++
from PyQt5.QtWidgets import QWidget, QGridLayout, QPushButton, QGraphicsOpacityEffect
from PyQt5.QtWidgets import QMainWindow, QAction, qApp, QApplication, QMenuBar
from PyQt5.QtCore import QUrl, QRect
from PyQt5.QtGui import QIcon

# msg = "Введите информацию о сервере"
# fieldNames = ["IP Сервера", "Логин", "Пароль"]
# title = 'FTP' 
# ftp_log = easygui.multpasswordbox(msg, title, fieldNames)

#@ ftp = ftplib.FTP('192.168.0.1', 'Artem', '1204')                        # #@

# ftp.cwd('/disk1_1')


class App(QWidget):
    def __init__(self):
        super().__init__()

        self.grid = QGridLayout(self)                                      # +++ self

        self.menubar = QMenuBar(self)
        self.file = self.menubar.addMenu('&Опции')
        self.exitAction = QAction(QIcon('cross-exit.ico'), '&Exit', self)
        self.exitAction.setShortcut('Ctrl+Q')
        self.exitAction.setStatusTip('Exit application')
        self.exitAction.triggered.connect(self.close)
