OK, I'm still not getting help on how to code for accessing a folder. So does anyone know where they keep sample scripts for people to go look and borrow??
If you are using Visual Studio install the ArcObjects SDK: ArcObjects SDK
Once installed just right-click in your class and choose either "ArcGIS Snippet Finder" or "Insert Snippet..." from the context menu.
Or just use ArcObjects Online as whuber noted.
