I can upload a File with flask by following Uploading Files:
<form> tag is marked with enctype=multipart/form-data and an <input type=file> is placed in that form.save() method of the file to save the file permanently somewhere on the filesystem.But I don't know how to upload folder or some files. I searched, and I found Uploading multiple files with Flask.
However, still I don't know how to upload a folder and files that belong to the folder.
Could you please tell how?

Source code of uploading file:
from flask import Flask,abort,render_template,request,redirect,url_for
from werkzeug import secure_filename
import os
app = Flask(__name__)
UPLOAD_FOLDER = './uploads'
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
@app.route('/')
def index():
return redirect(url_for('hello'))
@app.route('/hello/')
@app.route('/hello/<name>')
def hello(name = None):
return render_template('hello.html',name=name)
@app.route('/upload/',methods = ['GET','POST'])
def upload_file():
if request.method =='POST':
file = request.files['file']
if file:
filename = secure_filename(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'],filename))
return hello()
return render_template('file_upload.html')
if __name__ == '__main__':
app.run(debug = True)
template for file uploading(manage.py):
<!doctype html>
<title>Upload new File</title>
<h1>Upload new File</h1>
<form action='' method="POST" enctype="multipart/form-data">
<p><input type='file' name='file[]' multiple=''>
<input type='submit' value='upload'>
</p>
</form>

Handling file upload in Flask is very easy. It needs an HTML form with its enctype attribute set to 'multipart/form-data', posting the file to a URL. The URL handler fetches file from request. files[] object and saves it to the desired location.
Flask File Uploads Save uploads on the serverUse getlist — instead of [] or get — if multiple files were uploaded with the same field name. The objects in request. files have a save method which saves the file locally. Create a common directory to save the files to.
file = request.files['file']
change it to
file = request.files['file[]']
the issue here is that flask's app.config isn't relative to itself, it's absolute. so when you put:
UPLOAD_FOLDER = './uploads'
flask doesn't find this directory and returns a 500 error.
if you changed it to:
UPLOAD_FOLDER = '/tmp'
and then uploaded your file and navigated to the /tmp/ directory you would see it.
you will need to edit your path to the proper directory for the file to be uploaded properly.
