This is already broken because you're assuming a suitable version of qemu is 
preinstalled on the user's machine.  Once you have to install qemu, you can 
just as easily install a frontend to provide whatever user interface you 
want.

All modern filesystems have things called "directories" or "folders" than be 
be used to group sets of related files.
