MoI plug-in scripts usually come as a .zip file, where the .zip file contains 2 files, an .htm file and a .js file. To install the plug-in you need to unzip it and then copy those 2 files into MoI's commands folder.

Starting with MoI v4, MoI will now look for commands in 2 places, the commands folder inside the MoI application and also in the appdata Moi commands folder. It is recommended to copy plugins to the appdata folder so that new versions of MoI that you install will find them without needing any additional copying.

On Windows you can find the Moi appdata folder by typing Win+R to bring up the Windows "Run" dialog and then type in:
%AppData%\Moi\commands.

This might not be very clear. On my Windows 11 system, I have a “Moi” folder located at: user/AppData/Romaning/
Inside the “Moi” folder, I have a “Commands” folder where all the scripts are stored.Below is a selection of my scripts

Hi Wim,

re:
> how can I make it a bit easier when a new beta is installed?

Just to summarize - copy your commands into the Moi appdata commands folder instead of into the install folder.

If you put them there a new version will find them in that centralized location and you won't need to copy them around anymore.
