Question

I want to create a directory with some config file on the installation process and user home directory. My questions are:

-> how to create this directory while installing

Answer 1

You have access to some special folders for your application. You can save a file to the LocalFolder like this:

var file = await ApplicationData.Current.LocalFolder.CreateFileAsync("config.txt", CreationCollisionOption.ReplaceExisting);
await FileIO.WriteTextAsync(file, "Text to write to file");

and then retrieve it:

file = await ApplicationData.Current.LocalFolder.GetFileAsync("config.txt");

There’s also a RemoteFolder for files you want available to the user if they use your application on another device.

This folder can be found by going to something like “C:\Users\USERNAME\AppData\Local\Packages” and then finding the folder for your app.
