Maybe it's right in the directory the virtualized app resides. I was wondering though, if there's a way to bundle all changes back into the app to always have a single standalone executable? This would obviously have to recompile the executable everytime but I imagine it would be relatively straightforward inasmuch - take original Cameyo app as is + new data and write the new data onto a new exe that simply includes the original Cameyo app. This way you could save settings such as configuration options or even bits of user data.
