I would like to move the documentation to another partition on my Windows filesystem. Someone recommended "Global Options -> File Locations -> SystemHelpPath". It looked like it would do the trick but after I added the folder and moved the files, clicking on "documentation" in the start screen returns
"paclet:guide/WolframRoot" could not be found.
Windows version 8.1
Mathematica version 10.2
My "global preferences" and SystemHelpPath value, amended (see image below).
PS - what is the "x" in the last line of the SystemHepPath? I copied it directly from chat.
