How Google Chrome manages to upload the folder with preservation of structure to their Google Drive via a browser?

No add-ons and other client except the browser is not installed. Google chrome is able to get the file (scan or whatever it does) and pour it on the Google drive. The question is relevant, as it does, why it provides the access to the file system without permission. If you know something about the technology that he uses, please share. Can be used the FileSystem API and File API but not the fact.

Solution
By itself, Google Chrome is able to load folders, you can use this thing with the input element. But browser support this is not very good, so Google Drive is likely used by something else- for example you mentioned File API (it is likely that for different browsers they give different implementation).

If you about where my Chrome generally has read rights, then the answer is simple, and, most likely, was prelisten somewhere in the middle of the user agreement. By the way, if in the address bar in Chrome to enter file:/// it turns out "Medialogy Manager" - reads a file starting from the root (in Linux)
Thank you for the example. No. The question is not about the rights of the browser. You gave a great example. - Juana95 commented on July 9th 19 at 10:31
