I\'m trying to upload multiple files at once with my app. It recognizes when there are 2 or more files being selected. However, it will only upload the 1st file that is sele
I know this question is old, but after finding it and related ones, I was never able to get the multiple file upload working. So after a lot of banging my head against walls, I wanted to post a full example (.html and .gs) in case anyone in the future is looking for one to get started. This is working when I deploy it right now and will hopefully work for other people out there. Note that I just hardcoded the folder in the drive to use in the code.gs file, but that can be easily changed.

as @barragan's answer here is the best answer i found after hours and hours of searching for a question many people were asking, i've done a bit of development to improve the design a bit for others as a thanks. still a few bugs and chrome seems to run out of memory and give up with any file over 100MB
here's a live version

i wasn't able to get the text fields to send an email with the details out, and ran out of time before working out how to hook them up to a Google Spreadsheet, so for the moment they don't record the information added
as an added bonus, it looked fabulous with is in the form.html

i took it out again as some of the scripts being called in were causing issues. if anyone can fix them it they add a lot to the appearance and functionality of the form
*edit: i've been playing around with it and only around half of the files sent seem to arrive, so there are still some issues with both of the codes here atm
Joining the pile of older answers, but this really helped me when I implemented my own file multi upload for getting files into Google Drive using the DriveApp V3 api.
I wrote and posted my own solution here: https://github.com/CharlesPlucker/drive-multi-upload/
Improvements: - Handles multiple files sequentially - Handles large > 50MB files - Validation
I wrapped my google api calls into promises since I was running into timing issues when creating a folder and immediately trying to fetch it by name reference. Each one of my promises will only resolve when its file is fully uploaded. To get that working I had to use a Promise Factory. I'll be glad to explain this code if the need arises!
I updated and improved barragan's answer.
Advantages:
You can start with this example just to create the script and get to know the basics.
Then you can completely replace form.html with this:

You have to send a file at a time trough the script.run, here's my implementation with FileReaders/ReadAsURL, which makes the file a Base64 string, which can be easily passed around:
