Everything about Defragmentation
Technology for maintenance of file systems
In the maintenance of file systems, defragmentation is a process that reduces the degree of fragmentation, files that are stored in multiple segments that are not contiguous on the storage medium. It does this by physically organizing the contents of the mass storage device used to store files into the smallest number of contiguous regions. It also attempts to create larger regions of free space using compaction to impede the return of fragmentation. Wikipedia →
