Tendency of a file system to lay out the contents of files non-continuously to allow in-place modification of their contents.
Fragmentation can be remedied by re-organizing files and free space back into contiguous areas, a process called defragmentation.
Method and data structure that the operating system uses to control how data is stored and retrieved.
An example is the file system defragmentation utilities.
Phenomenon in which storage space, main storage or secondary storage, is used inefficiently, reducing capacity or performance and often both.
For example, the primary job of a defragmentation tool is to rearrange blocks on disk so that the blocks of each file are contiguous.
Memory management scheme by which a computer stores and retrieves data from secondary storage for use in main memory.
Defragmenting the page file is also occasionally recommended to improve performance when a Windows system is chronically using much more memory than its total physical memory.
Major release of the Windows NT operating system developed by Microsoft and oriented towards businesses.
File system defragmentation support
Proprietary journaling file system developed by Microsoft.
It is a feature that FAT does not provide and critical for NTFS to ensure that its complex internal data structures will remain consistent in case of system crashes or data moves performed by the defragmentation API, and allow easy rollback of uncommitted changes to these critical data structures when the volume is remounted.
Electro-mechanical data storage device that stores and retrieves digital data using magnetic storage and one or more rigid rapidly rotating platters coated with magnetic material.
Defragmentation is a procedure used to minimize delay in retrieving data by moving related items to physically proximate areas on the disk.
Computer storage format that combines a file system based on the copy-on-write (COW) principle with a logical volume manager (not to be confused with Linux's LVM), developed together.
In July 2011, Btrfs automatic defragmentation and scrubbing features were merged into version 3.0 of the Linux kernel mainline.
Microsoft Drive Optimizer (formerly Disk Defragmenter) is a utility in Microsoft Windows designed to increase data access speed by rearranging files stored on a disk to occupy contiguous storage locations, a technique called defragmentation.
Solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage.
Defragmentation should be disabled on solid-state drives because the location of the file components on an SSD doesn't significantly impact its performance, but moving the files to make them contiguous using the Windows Defrag routine will cause unnecessary write wear on the limited number of P/E cycles on the SSD.
