How can I paste an entire file from clipboard to a folder?

[DeaD_EyE]

You can copy text from clipboard with Tkinter or Pyperclip.
Tkinter is shipped together with Python.

What you could not do, is getting raw bytes from a copied image to clipboard.
Tkinter doesn't seem to support it.

If you copy a File to your Clipbaord, you'll get a String back.
This code should work and return a Path object, if the Path was valid.
Otherwise it return None.

from pathlib import Path
from tkinter import Tk, TclError
 
 
def get_clipboard_as_path():
    root = Tk()
    root.withdraw()
    try:
        content = root.selection_get(selection="CLIPBOARD")
    except TclError:
        return None
    finally:
        root.destroy()
 
    file = Path(content)
   
    try:
        if file.exists():
            return file
    except OSError:
        pass
   
    return None
 
 
# get the path
my_path = get_clipboard_as_path()
# my_path could be None
if my_path:
    print(f'The path is {my_path}')
    # if my_path is a directory, find all python files
    if my_path.is_dir():
        print('The path is a directory')
        for file in my_path.glob('*.py'):
            print(file)
    else:
        print('The path is a file')
        with my_path.open() as fd:
            header = fd.readline()
            print('First line:')
            print(header)
else:
    print('It was not a Path, maybe a image or something else')

If win32clipboard has a better support for clipboard, you should use this.
Tkinter is very limited.
