I am using pypdfium2 to read text from a PDF and then later move it to a different folder, but I am getting the same error telling me that it is open and can’t be moved.

How do I properly close the document for it to be moved? I added the True parameter for autoclose but no change.

I will add that stopping my program still means I can’t move the file around in file explorer. I need to close out of Spyder entirely before I can move these files around.

    observer = watchdog.observers.Observer()
    event_handler = Handler()
    observer.schedule(event_handler, path=src_path, recursive = False)
    observer.start()
    try:
        while True:
            time.sleep(15)
    except KeyboardInterrupt:
        observer.stop()
        print("Observer Stopped")
        
    observer.join()

I tried using a with(open) statement but I got errors with pdfium and it didn’t make any difference.
