NTFS is a proprietary journaling file system developed by Microsoft. Starting with Windows NT 3.1, it is the default file system of the Windows NT family.
Linux has several filesystem drivers for the File Allocation Table (FAT) filesystem format. These are commonly known by the names used in the mount command to invoke particular drivers in the kernel: msdos, vfat, and umsdos.
In the maintenance of file systems, defragmentation is a process that reduces the degree of fragmentation. 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. Some defragmentation utilities try to keep smaller files within a single directory together, as they are often accessed in sequence.
In computing, a hard link is a directory entry that associates a name with a file on a file system. All directory-based file systems must have at least one hard link giving the original name for each file. The term “hard link” is usually only used in file systems that allow more than one hard link for the same file.
PartitionMagic is a utility software for hard disk drive partitioning originally made by PowerQuest, but now owned by Symantec. As of December 8, 2009, the Symantec website stated that they no longer offer Partition Magic. The program runs on Microsoft Windows operating systems including Windows 2000 and Windows XP, but the application is incompatible with Windows Vista and later versions. A bootable disk for partitioning drives must be used instead. The utility can also be run from a bootable CD-ROM and enables creation and modification of partitions. Existing partitions can be resized without loss of data.
The fstab file is a system configuration file commonly found at /etc/fstab on Unix and Unix-like computer systems. In Linux, it is part of the util-linux package. The fstab file typically lists all available disk partitions and other types of file systems and data sources that are not necessarily disk-based, and indicates how they are to be initialized or otherwise integrated into the larger file system structure.
In computing, a file system or filesystem, controls how data is stored and retrieved. Without a file system, data placed in a storage medium would be one large body of data with no way to tell where one piece of data stops and the next begins. By separating the data into pieces and giving each piece a name, the data is easily isolated and identified. Taking its name from the way paper-based data management system is named, each group of data is called a "file". The structure and logic rules used to manage the groups of data and their names is called a "file system".
Shadow Copy is a technology included in Microsoft Windows that can create backup copies or snapshots of computer files or volumes, even when they are in use. It is implemented as a Windows service called the Volume Shadow Copy service. A software VSS provider service is also included as part of Windows to be used by Windows applications. Shadow Copy technology requires either the Windows NTFS or ReFS filesystems in order to create and store shadow copies. Shadow Copies can be created on local and external volumes by any Windows component that uses this technology, such as when creating a scheduled Windows Backup or automatic System Restore point.
In computing, CHKDSK is a system tool and command in DOS, Digital Research FlexOS, IBM/Toshiba 4690 OS, IBM OS/2, Microsoft Windows and related operating systems. It verifies the file system integrity of a volume and fixes logical file system errors. It is similar to the fsck command in Unix and similar to Microsoft ScanDisk which co-existed with CHKDSK in Windows 9x and MS-DOS 6.x.
Extended file attributes are file system features that enable users to associate computer files with metadata not interpreted by the filesystem, whereas regular attributes have a purpose strictly defined by the filesystem. Unlike forks, which can usually be as large as the maximum file size, extended attributes are usually limited in size to a value significantly smaller than the maximum file size. Typical uses include storing the author of a document, the character encoding of a plain-text document, or a checksum, cryptographic hash or digital certificate, and discretionary access control information.
The following tables compare general and technical information for a number of file systems.
The Sleuth Kit (TSK) is a library and collection of Unix- and Windows-based utilities to facilitate the forensic analysis of computer systems. It was written and is maintained primarily by digital investigator Brian Carrier.
chattr is the command in the GNU operating system that allows a user to set certain attributes of a file. lsattr is the command that displays the attributes of a file.
In computer operating systems, mkfs is a command used to format a block storage device with a specific file system. The command is part of Unix and Unix-like operating systems. In Unix, a block storage device must be formatted with a file system before it can be mounted and accessed through the operating system's filesystem hierarchy.
In computing, label is a command included with some operating systems. It is used to create, change, or delete a volume label on a logical drive, such as a hard disk partition or a floppy disk. Used without parameters, label changes the current volume label or deletes the existing label.
In computing, format, a command-line utility that carries out disk formatting. It is a component of various operating systems, including 86-DOS, MS-DOS, IBM PC DOS and OS/2, Microsoft Windows and ReactOS.
libguestfs is a C library and a set of tools for accessing and modifying virtual disk images used in platform virtualization. The tools can be used for viewing and editing virtual machines (VMs) managed by libvirt and files inside VMs, scripting changes to VMs, creating VMs, and much else besides.
Resilient File System (ReFS), codenamed "Protogon", is a Microsoft proprietary file system introduced with Windows Server 2012 with the intent of becoming the "next generation" file system after NTFS.
Partclone is a partition clone and restore tool. It provides utilities to back up and restore partitions and is designed for higher compatibility of the file system library. It is developed by the NCHC Free Software Labs in Taiwan. It is the default backup application in Clonezilla, FOG from version 1.00 and Redo Backup and Recovery which is simply a front end to partclone. It supports many file systems and has good performance, as it skips portions of the file system marked as free space.
