cam2pc can also be configured to display an additional entry in the contextual menu that appears when you right-click on a folder in Explorer. This menu allows you to easily browse any folder with cam2pc's Image Browser directly from Explorer.
Go to the Shell Integration section of the Options dialog and click the "Integrate cam2pc into Explorer" checkbox.
Now if you right-click on a folder in Windows Explorer, you should see a "Browse with cam2pc" entry. Select it and cam2pc should be automatically run in this particular folder.
