Expansion UserPreset: Delete Problem.

[CyberGen]

I'm trying to make a UI button to delete an Expansion UserPreset. How do I tell HISE to delete files from the current expansion UserPresets Folder, rather than from the main UserPresets folder?

What I have so far works but only for presets in the main UserPreset Folder.

Could you help me figure out what I'm missing?

//	DELETE EXPANSION PRESET	(not working)
	inline function ondeletePresetControl(component, value)
	{	
		if (value)
		{

		//	Define User Preset Folder: (incomplete)
			reg usrPreFolder = FileSystem.getFolder(FileSystem.UserPresets);
		//	Check if folder is directory:
			Console.print(usrPreFolder.isDirectory());
		//	Current Preset Name:
			reg currentPreset = Engine.getCurrentUserPresetName();
	 	//	Define File to be Deleted:
	 		reg toDelete = usrPreFolder.getChildFile(currentPreset + ".preset");
		//	Check if it is a File:
	 		Console.print(toDelete.isFile());
	 	//	Yes or no window:					
			Engine.showYesNoWindow("Delete", "Are you sure you want to delete preset:  " + currentPreset + " ?", function(response)
			{
			//	Import file name:	
				reg f = toDelete;

			// 	IF Delete Confirmed:
				if (response)
				{
				//	Delete File:
					f.deleteFileOrDirectory();
				//	Load next preset:
					Engine.loadNextUserPreset(true);
				}
			});		
		}
	};
	Content.getComponent("deletePreset").setControlCallback(ondeletePresetControl);

@RastaChess Only declare local variables inside inline functions, no var, const, or reg.

You can get the user presets folder for an expansion like so:

const dir = FileSystem.getFolder(FileSystem.AppData).getChildFile("Expansions").getChildFile("Expansion Name").getChildFile("User Presets");

@d-healey Thank you So Very Much.

I was able to get to the expansion UserPreset folder.

A copule follow up questions if I may.

1 .- How do I get the current expansion name as a string to be inserted in the dir formula?

2.- I made my dir point to the UserPreset Folder from inside my project folder/expansions, rather than the AppData one as you suggested, only cuz that is where I have the presets. Does that matter for when I export the plug in? should I change to the AppData folder before exporting?

const dir = FileSystem.getFolder(FileSystem.Expansions).getChildFile("Expansion Name").getChildFile("UserPresets");

@RastaChess said in Expansion UserPreset: Delete Problem.:

1. Using getProperties(): https://youtu.be/VsQTOxOOd9s?t=593
2. You can put a link file in your project's expansions folder to redirect it to the one in appdata.

@d-healey Thanks for sharing. I had looked at that video.

I still can't find a straight forward way to get the actual current expansion name as a string.
Or a way to directly get to the UserPreset Folder of the active Expansion without manually feeding HISE the active expansion name. I need it to change automatically when the user changes expansions.

local e = expHandler.getCurrentExpansion();
local expName = e.getProperties().Name;

And I just remembered a shortcut to get the preset folder for an expansion.

e.getRootFolder().getChildFile("User Presets");
