File Security and Access Rights. Because files are securable objects, access to them is regulated by the access-control model that governs access to all other securable objects in Windows. For a detailed explanation of this model, see Access Control. You can specify a security descriptor for a file or directory when you call the CreateFile, CreateDirectory, or CreateDirectoryEx function. If you specify NULL for the lpSecurityAttributes parameter, the file or directory gets a default security descriptor.
The typical width is usually 50 and 60 inches. A good example of a pickup with standard bed dimensions is the GMC Sierra. Its bed is 50 inches wide and 6.5 ft long. You can also use a Nissan Titan because it has a standard bed. Its bed is 60 inches wide and 6.5 feet long.
On full-size trucks, a short bed is most often about 6.5 ft. Short beds are sufficient for the majority of pickup drivers, because they still pack the cargo room for most jobs without being too cumbersome for the average driver to maneuver in everyday situations.
