I would like to have an icon in DO that when clicked copied the complete path of the currently highlighted file/folder to the clipboard, so I could paste it in to a text document. How would I do that?
Create a button with the command..
or Clipboard COPYNAMES nopaths
.. if you only need the filename(s).
Make an new button containing the command
I'm sorry, how do I make a new button?
There are lots of examples showing how to create buttons in the Buttons & Toolbars forum, there's also a FAQ.
Also, there's a toolbar editing video in the Tutorials forum.
what command for a button, to copy just the name (without path and extension!) to clipboard?
See the bottom of the FAQ on copying names to the clipboard.
