file removal on uninstall

[hhale21]

My install is putting files in sub-folders of Common Application Data -> [|Manufacturer]->[|ProductName]
When I uninstall some files are removed others not. What controls whether the file is removed or not? Is it if they where modified since being installed?
Because if that is the case then it is not consistent. If I modify 2 different files, then uninstall it always removes one and but not the other.

I don't want any files removed under "Common Application Data". Some are configuration files and an uninstall and re-install results in the loss of changes made by the user.

Hello,

Files that were not installed with your installer, will not be uninstalled. For example, configuration files created by your application will not be uninstalled.

For preserving files after an uninstall, please see our guide on preventing files' uninstall.

Best regards,
