Local documentation installation drive

I am unable to install the local documentation to a drive other than the c: drive. The installer for the documentation does not expose the option to redirect the installation. I have successfully installed Mathmatica to the D: drive, but the documentation still shows up on the c: drive. It’s 8GB so it puts a big dent in my c: drive and I need to move it.

Any suggestions?

Move the documentation folder,normally
“C:\Program Files\Wolfram Research\Mathematica\13.2\Documentation”
into your
“D:\Program Files\Wolfram Research\Mathematica\13.2\Documentation”

Go to menu Edit/preferences last entry Avanced and open OptionInspector

There you find the node FileLocations with the search tree for Help. Klick on the little square on the right. A window pops up with the paths encoded as Mathematica commands with $systemvaraibles as values.. The given file locations are

$UserBaseDirectory
$BaseDirectory
$InstallationDirectory
Out[1]= C:\Users\mef\AppData\Roaming\Mathematica
Out[2]= C:\ProgramData\Mathematica
Out[3]= C:\Program Files\Wolfram Research\Mathematica\13.2

If the new directory is in one of these standard system paths it should work now.

I run into the same problem on Windows 10, Mathematica 13.1. The Windows installation files automatically install the documentation in C drive irrespective of the chosen installation directory for Mathematica.

What has worked for me was moving the folder

C:\Users\[username]\AppData\Local\Programs\Common\Wolfram␣Research\Documentation.en-us\[version]\Documentation\English

to

D:\Program␣Files\Wolfram␣Research\Mathematica\[version]\Documentation\English

where

D:\Program␣Files\Wolfram␣Research\Mathematica\[version]

is the Mathematica’s $InstallationDirectory.

At the first run of Mathematica after moving the files, it took about half a minute to open the documentation. Afterwards, it works at normal speed.

I found the folder locations in the official description of the current system file organisation of Wolfram language and documentation:
