I don't know if it's a standard, but at the last 2 places I've used Citrix, all user's had a mapping to a user folder on Citrix. I think it's M:. So you will just have to verify your app can handle looking in M: for it's config file. M: is map rooted to the share + the user name, so you can put any user specific data there.

>>As I stated before, local files would be files the user would need to import/export from your app. You will need to take a few extra steps to make sure they are pointing to a drive on their computer, rather then the server.
