By default, a user's customized Maple settings (e.g. which palettes are expanded in the GUI, and whether smart operators are enabled) are stored in the preferences file:
The location can be changed, for example, to use a common file for all users of a single machine. Suppose, for instance, you want to have the file stored in the following folder:
C:\Program Files\Maple 2021\Application Data\Maple
Note that, depending on the folder, you may need to run Maple "as administrator".
To achieve this, you can perform these steps:
Open the file
C:\Program Files\Maple 2021\bin.X86_64_WINDOWS\maplelauncher.l4j.ini
in a text editor, like Notepad, Wordpad, or Notepad++. You may need to open the editor "as administrator".
Insert the line
-Dmaple.user.home="C:/Program Files/Maple 2021/Application Data/Maple/"
at the bottom, and then save the file.
Note: If you want keep the old settings, you will need to place the old preferences file in the new location, because otherwise the next time Maple closes, it will create a new preferences file with the default settings.
