It worked wonderfully, it saved my life, thanks!

t worked wonderfully!! Thanks a lot, you save my time!

This is awsome. It helped me save 3 hrs everyday.!!
Thank you for posting this.

Can anyone tell me that where I have to put wd-drop-file.js in project?

@florentbr
Worked great with files!
But I currently need to drag and drop folder. What JS script can I use for that?

Works for me as well) Thanks a lot!

I recently needed to do this. I've extended @florenbr 's code to check whether the path given to drop_files() is a directory, and if so to iterate through all the files in the directory and append them to the master list.

    driver = element.parent
    isLocal = not driver._is_remote or "127.0.0.1" in driver.command_executor._url

    for path_to_upload in (
        paths_to_upload if isinstance(paths_to_upload, list) else [paths_to_upload]

            for path, _, files in walk(path_to_upload):
                all_files += [join(path, name) for name in files]

            for file in all_files:
                files_to_upload.append(file if isLocal else element._upload(file))

                path_to_upload if isLocal else element._upload(path_to_upload)

not working for me .. getting error TypeError e.webkitGetAsEntry is not a function (java)

@sandip2421, i've added the webkitGetAsEntry even though it's non standard. It should work as long as the webpage doesn't try to access the filesystem api.

I used this code in headless mode but this error occurred var ex = new Error('Element not interactable');, can you help me? thanks

@carl-pki For headless, you need to set the window size. this is what I do:

if data['headless']:
    options = Options()
    options.add_argument('--headless')
    options.add_argument('--disable-gpu')  # Last I checked this was necessary.
    driver = webdriver.Chrome(options=options)
else:
    driver = webdriver.Chrome()
driver.set_window_size(1547, 1102)
driver.implicitly_wait(2400)
driver.get("https://rumble.com/")
driver.find_element(..........

As You can see, I am using Chrome... But I'm sure it applies to other browsers

and trying to use this code in an implementation to upload files with this method to Google Drive but notice that it stays in this can someone try?

here the code...

with this code it stays on this screen and does not go up.

worked straight out of the box!! o7
the only solution on the internet that actually solves the problem without beating around the bush.

Hi guys,
I tried to test it and get the error message.

selenium.common.exceptions.WebDriverException: Message: <unknown>: Element not interactable

Can any one can help me resolve it?

Frikkn unbelievable thank you!
