Is there a way to know which apps are from PortableApps and which aren't?

I have multiple apps that are portable but aren't downloaded from PortableApps. The problem comes when I get a new version prompt, I don't know if I should update it with the app updater or wait for PortableApps to create an update themselves. It would be easier if there was a way to know if a software was downloaded using the platform or not (I used to use the "Portable" word in the name of the folder, but I think there are some which don't have the word in it and were still downloaded using PortableApps). Does anyone know how to work around this?
