For installer, detect if the specified folder contains instances folder. about prismlauncher HOT 4 CLOSED

Prism installer doesn't delete the instance folder, nor does the uninstall of prism.
Usually, prism has two folders that it cares about:

• where the executable is located
• and the data directory = where your configs and instances are usually located

So when reinstalling/uninstalling prism the only affected folder is where the executable is located and even there the files that are modified are limited to the ones created by the prism installer.
So when you install my suggestion is if you do not have a reason to change the install path do not do it. But if you do prism will not care about where is installed as the data directory will always point toward the same location on the system.
I will close this as not planned.
If you have trouble installing/updating let me know in this issue or better you can join Prism discord and ask there.

I see. Appreciate your answer.

Normally I won't do that, but I thought I should because at the past I'm using portable version of MultiMc which is in a custom location, so I thought my prism install might be on custom location too, so I looked up the path and changed it.

Good to know that it doesn't actually remove other files! But why is it scanning all the files, although they will remain untouched?

Thanks, I've already installed it correctly before opening this issue.

I will presume that is to collect the files that need to be deleted.
The portable update is another story as you usually just need to extract over the old portable(there may be caveats to that like before extracting you would need to delete some files)
