Unlike arrays, the size for a linked list is not pre-defined, allowing the linked list to increase or decrease in size as the program runs. This is possible because to insert or delete from a linked list, the pointers need to be updated accordingly. NettetLinked allocation solves all problems of contiguous allocation. With linked allocation, each file is a linked list of disk blocks; The disk blocks may be scattered anywhere on the disk. The directory contains a pointer to the first and last blocks of the file.
