One problem with contiguous allocation is that the user must preallocate
enough space for each file. If the file grows to be larger than the
space allocated for it, special actions must be taken. One solution to this
problem is to define a file structure consisting of an initial contiguous
area (of a specified size). If this area is filled, the operating system
automatically defines an overflow area that is linked to the initial
contiguous area. If the overflow area is filled, another overflow area
is allocated. Compare this implementation of a file with the standard
contiguous and linked implementations.
