Hi All,
As far as I know, ghuser files won’t be loaded from outside of “%appdata%\Grasshopper\UserObjects”.
Is it possible to do it like gha file linked by ghlink?
Thanks,

It looks like in Grasshopper accepts more than one folder for loading userobjects from Grasshopper.Folders.UserObjectFolders.
How can we add anew folder to the current folder list before loading an instance of the Grasshopper? It’s currently the default UserObjects folder and one random folder which is added by Weaverbird plugin. I’m not sure how/when the second one has been added.
This might potentially work (haven’t tested), but this is how Ironbug loads openstudio.dll. This is executed when GH is loading.
Never mind, adding userObjectFolders under PriorityLoad() doesn’t work.
Did you ever figure this out?
The Pancake plug-in will give you options to load user objects elsewhere.

That won’t do because UserObjectFolders is generated per call and never reflected back into GH.
Any news on that?
In case anyone else is still trying to do this, I’ve found a workaround which works for our case of trying to create a way of sharing user objects between people in our company.
This works by copying the .ghuser files you would like to share from a shared drive to the local system. The key is where the copying script runs. I’ve only be able to get this work by subscribing to the DocumentAdded event by using the PriorityLoad method in GH_AssemblyPriority. You have to build this into a plugin for it run. But that plugin can be loaded through a .ghlink. The user objects will be copied access each time a new document is opened.
This probably isn’t the best way to do it as your altering files which are actively being used by grasshopper but it seems to work for us without any issues. I’ve tried running the code as part of the CanvasCreatedEventHandler or directly in PriorityLoad but although the user objects get copied they don’t get populated to the components cache. My best bet is this is due to the order of operations when grasshopper is loaded.
Adding this class to a plugin will enable the functionality.
