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 initialization file:
C:\Users\%USERNAME%\AppData\Roaming\Maple\2019\Maple.ini
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 2019\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 2019\bin.X86_64_WINDOWS\maplelauncher.l4j.iniin 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 2019/Application Data/Maple/"at the bottom, and then save the file.
-
Start Maple.
Note: If you want keep the old settings, you will need to place the old initialization file in the new location, because otherwise the next time Maple closes, it will create a new initialization file with the default settings.
