Most folder and drive listings within the FolderSizes interface can be right-clicked to display context menu containing various features.
Places where you can right-click folder / file / drive names include:
•Folder Browser Panel
•Primary Report Detail View
•Drive Space View
•File Reports (most)
The FolderSizes context menu has a wide range of functionality, including unique "Cmd Prompt From Folder" and "Explore From Folder" capabilities that work even when right-clicking on a file (the action then references the containing folder).
