byte fragment. If the file is extended by another 500 bytes, another allocation of

a 512 byte fragment will be made to this file. So far, two allocation operations

have already been performed. However, with a file system fragment size of 4KB,

the first file extension operation would have involved one allocation to this file of

a 4KB fragment and the second file extension operation would not have resulted

in an allocation as there would have been sufficient space from the first

allocation. The number of allocations made in the file system using a 512 byte

fragment could have been minimized if the two separate file extension

operations were performed ...
