I have found a way to add "copy path only" (option/general/context menu).
But it adds unnecessary double quotes " ". And the last \ is not added.
Example : "C:\test"
Desired result :
C:\test\
I am asking this because I often saving pdf files in different folders of my computer (win7 64). So I need to copy/paste the correct path in the pdf saving dialog box (and keeping the original pdf filename).
