I use this script for years and I`m very happy with it. Simply select a file or directory in Windows Explorer and copy it`s path to the clipboard directly from the context menu.
To install it, run a command shell as admin and call the script without an argument. After that it is installed and can be used from the context menu.
Or you can do Shift + Right Click; select Copy as path.
Ich wollte einfach einen netten Gruss da lassen. Bin eben auf eure Websiete gestossen.
