I mean open an Explorer folder, then select a file, drag and drop it into the file upload area of Google Chrome.
In the past, to upload a file, you needed to click a button, and then select a local file. It would pop up a file selection dialog box. Finally, the file name would be written into a text box on the web page.
This text box cannot be set directly, only by selecting a file.


Now a new generation of web browsers, it can change a way, drag and drop files directly to the browser page.
How to automate this step through the program?
For example, 100% simulate the mouse to select a file, and then drag and drop it.

Or operate in the background through Google Drive.
