Is there a way to determine whether the After Effects application was started by clicking on the Program icon or by double clicking an .aep file. Basically I'd like a script in my startup folder to run if the application was started by clicking on the application icon and to not run if an already existing project was double clicked to open After Effects.

Thanks for any advice.

Hi Rob,

Assuming your existing project actually has items in it, you might be able to check if app.project.numItems > 0 to proceed with the script or not.

Note that you can't just check if the app.project.file == null because a project saved in an earlier version of After Effects will come in as untitled.

Hope this helps.

At first I didn't think so. After Effects runs the startup script before opening the project, and the script doesn't have access to that information.

But I have managed to come up with this:

{
	function check() {
		//if (app.project.file == null) {
		if (app.project.numItems == 0) {
			writeLn("AE was opened with no project");
		} else {
			writeLn("AE was opened with a project");
		}
	}

	app.scheduleTask("check()",1000,repeat=false)	
}

I'm using app.scheduleTask to get the main part of the script to run one second later. This seems to be enough time for a project to start loading if there is one, and the script then runs after the project has loaded.

At first I was checking if the project had a file path (app.project.file == null) but this wasn't catching projects that opened as untitled.aep due to importing an older project version, so I changed it to check if the project was empty (app.project.numItems == 0).

Thanks for your help Paul. This worked well for my particular application.
