AGP can make connections to root directories (C:, D:, etc.). As show in the screen grab, right-click the Folders item, select the Add Folder Connection in the Catalog Pane, navigate to Computer on the left side of the Add Folder Connection UI, select the root drive you wish - C: for example - then click OK. It's now added to your AGP project. Further if you want AGP to remember the root drive in all new AGP projects, right click the root directory in the Catalog Pane and select Add to New Projects. Now AGP will always remember to add the root drive to all new projects.
