Where is the data for Properties.Settings.Default saved?
c#, settings, wpf
Solution
Since you selected user scope, they are saved in each user profile directory, more specifically, inside the `AppData` folder of the user profile in a file named `user.config`.
The full path is dependent of the application.
In Windows 7 without roaming profile and with an Windows Forms Application named `Example.Settings.CustomClass` I'm getting the following folder:
C:\Users\[user]\AppData\Local\Microsoft\Example.Settings.CustomCl_Url_3qoqzcgn1lbyw2zx3oz1o3rsw2anyjsn\1.0.0.0
Also note that they are saved taking in consideration the version of your application and that the values stored in `App.config` are the default values used for a new user.
Problem
In my WPF application, I click on Settings.settings in the Solution Explorer and enter a StringCollection variable with a User scope: in my app.config I see that they are saved there: ``` <userSettings> <TestSettings.Properties.Settings> <setting name="Paths" serializeAs="Xml"> <value> <ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <string>one</string> <string>two</string> <string>three</string> <string>four</string> <string>five</string> <string>six</string> <string>seven</string> </ArrayOfString> </value> </setting> </TestSettings.Properties.Settings> </userSettings> ``` then I run my application and with this code: ``` StringCollection paths = Properties.Settings.Default.Paths; Properties.Settings.Default.Paths.Add("added in code"); Properties.Settings.Default.Save(); foreach (var path in paths) { System.Console.WriteLine(path); } ``` which gives me this output: ``` one two three four five six seven added in code ``` I run the application again and it gives me this output: ``` one two three four five six seven added in code added in code ``` But I look at my app.config again and it still has the original values: ``` <userSettings> <TestSettings.Properties.Settings> <setting name="Paths" serializeAs="Xml"> <value> <ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <string>one</string> <string>two</string> <string>three</string> <string>four</string> <string>five</string> <string>six</string> <string>seven</string> </ArrayOfString> </value> </setting> </TestSettings.Properties.Settings> </userSettings> ``` Where are the values that are added by the application being saved?
