Upload a whole directory through an HTML form

Question

Is it possible to upload a folder with a file input in the browser?

I searched and found out that this might be a browser limitation and that I might need to use a Java Applet or Flash.

Answer 1

It's becoming possible with use of webkitdirectory.

<input type="file" webkitdirectory directory multiple />

Supported since Firefox 50, Chrome 30, Safari 11.1, Edge 14, but not on most mobile browsers as of 2019: https://caniuse.com/#feat=input-file-directory
