Delete off version folder in Application Data folder

[enigma]

Hi,

I found that if we access Application.UserAppDataPath property in our .Net program, then an extra folder named %versionNumber% will be created inside the ApplicationData folder.

My question is, during the uninstallation time, I want the AI to delete this folder. So let say I uninstall "MyApp" version 1.0.0.0 from the computer, then I want the folder named "1.0.0.0" inside the ApplicationData is also removed.

Is there anyway to do this?

Hi,

There is a similar discussion on the forum, please take a look:

Note that instead of "PROPERTY" you can use "AppDataFolder" which is resolved at runtime to "Documents and Settings\[current_user]\Application Data".

Hi, thank you for your reply.

However, there are two problems I encountered with the above method:

• If I set the Session.Property("AppDataFolder"), I can't delete the application data because there is no permission for me to do this. Is there anyway to override this permission thing?
• Actually, I need to delete a folder inside the Application Data Folder, not the application data itself. I don't know how to set the path for this one. The folder that I want to delete always has the product version as the folder name. So, if the application version is 1.0.0.0, the folder I want to delete is [AppDataFolder]\1.0.0.0. I set the path as "ApDataFolder\ProductVersion",ession.Property("AppDataFolder\ProductVersion") returns me a null string

Note that it is not recommended to delete the Application Data folder.

What I meant in my previous post was that you can use AppDataFolder to find the folder that will be deleted. Therefore you will make this modification:

Code: Select all

pathToFolder=Session.Property("AppDataFolder")&Session.Property("ProductVersion")
