Everything about File system fragmentation
Storage of a file in non-contiguous blocks
File system fragmentation, sometimes called file system aging, is a characteristic of a file system that stores files in non-contiguous blocks. It is a special case of data fragmentation. File system fragmentation negatively impacts seek time for disk storage, which lowers throughput. Fragmentation can be eliminated by re-organizing files as contiguous areas, a process called defragmentation. Wikipedia →
