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.
Long Bed: The long bed is usually a foot or two longer than the short bed and is more popular on trucks such as commercial work trucks or farm trucks. The long bed style is sometimes referred to as a long box. Compact long beds are generally 7 ft (2.1 m) long and full-size long beds are generally 8 ft (2.4 m) long. Full-size long beds offer the advantage of carrying a standard-size 4 ftÃ8 ft sheet of plywood with the tailgate closed adding versatility for people using the truck for construction on contract work.
