How does one create an installer that will guarantee that no matter where a user chooses to save file to the files do not get removed during installation of a new build?

For instance if a user chooses to save files in the app folder, then during an update the files would be removed. How can a developer prevent this from occurring? We can set a default location BUT ultimately a user can choose to save information where ever they wish to. Seems like this is a problem? At least with an app I have currently. Or so it would seem. Is it truly possible to cover every possible location that a user MAY decide to save information to?

You don't

Users should never save to the app folder. The app should default to Documents or Data as a fallback.

Sometimes, the impossible can become possible, if you're awesome!

agreed

So it is impossible to prevent loss of data if a user choose to go against convention?

Very Rare

I've only see a user do this maybe twice before. It's completely counterintuitive. It's like saving something to Program Files (which will also generally cause your data to go bye bye). And there's a file with a warning in it right in the App directory.

AS I expected, just trying to make sure I cover all bases on all my apps, did not want to be doing any thing htat was incorrect

But remember:

There is a reason why RemoveAppDirectory is true by default.
