Don't worry, the apps know where the files are when you need them. And you only need them when you are using the app, after all you will own nothing and you will be... wait now that I think about it, you do have the files somewhere on your hard drive, right? so they're technically actually yours, right? my mistake, yeah so nothing to worry here.

And there are some rare exceptions of those apps that uploads your stuff to the cloud for security and for easy backups, such a great technology because if you ever lose your computer you can just buy another one and the 'files' will be magically there (as long as you keep paying the app subscription)! Hopefully the author also implemented the app in a way that can be used offline.

Btw you will need the newest version of the computer because your apps updated so that's also great because new features are good! Your files are basically your creation, you can't just leave them behind.
