FASTOPEN (CONFIG
In computing, FASTOPEN is a DOS terminate-and-stay-resident command, introduced in MS-DOS version 3.3, that provides accelerated access to frequently-used files and directories. The command is also available in SISNE plus. Overview The command works with hard disks, but not with diskettes (probably for security when swapping) or with network drives (probably because such drives do not offer block-level access, only file-level access). It is possible to specify for which drives should operate, how many files and directories should be cached on each (10 by default, up to 999 total), how many regions for each drive should be cached and whether the cache should be located in conventional or expanded memory. If a disk defragmenter tool is used, or if Windows Explorer is to move files or directories, while is installed, it is necessary to reboot the computer afterwards, because would remember the old position of files and directories, causing MS-DOS to display garbage if e.g. " DIR ...

Defragmenter
In the maintenance of file systems, defragmentation is a process that reduces the degree of file system fragmentation, fragmentation. It does this by physically organizing the contents of the mass storage device used to store computer file, files into the smallest number of Contiguous data storage, contiguous regions (fragments, ''extents''). It also attempts to create larger regions of free space using Data compaction, 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. Defragmentation is advantageous and relevant to file systems on electromechanical Disk storage, disk drives (hard disk drives, Floppy disk, floppy disk drives and Optical disc drive, optical disk media). The movement of the Disk read-and-write head, hard drive's read/write heads over different areas of the disk when accessing fragmented files is slower, compared to accessing the ent ...

List Of DOS Commands
This article presents a list of commands used by DOS operating systems, especially as used on x86-based IBM PC compatibles (PCs). Other DOS operating systems are not part of the scope of this list. In DOS, many standard system commands were provided for common tasks such as listing files on a disk or moving files. Some commands were built into the command interpreter, others existed as external commands on disk. Over the several generations of DOS, commands were added for the additional functions of the operating system. In the current Microsoft Windows operating system, a text-mode command prompt window, cmd.exe, can still be used. Command processing The command interpreter for DOS runs when no application programs are running. When an application exits, if the transient portion of the command interpreter in memory was overwritten, DOS will reload it from disk. Some commands are internal—built into COMMAND.COM; others are external commands stored on disk. When the user typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SmartDrive
SmartDrive (or SMARTDRV) is a Page cache, disk caching program shipped with MS-DOS versions 4.01 through 6.22 and Windows 3.0 through Windows 3.11. It improves Data transfer rate (disk drive), data transfer rates by storing frequently accessed data in random-access memory (RAM). Early versions of SmartDrive were loaded through a device driver named . Versions 4.0 and later were loaded through an executable file named , which could be run at user's discretion or at boot time via . However, also includes a double-buffering driver that should be loaded through . Version 4.0 also introduced 32-bit disk access and could reduce its footprint in conventional memory (the first 640 kilobytes of memory which was critical to DOS) by running in upper memory area (the 384 kilobytes of memory located beyond the conventional memory). A cloaked variant of SmartDrive utilizing the Helix Cloaking Application Program Interface, API was available from Helix Software. On Intel 80386 processors, it ...

NTVDM
Virtual DOS machines (VDM) refer to a technology that allows running 16-bit/32-bit DOS and 16-bit Windows programs when there is already another operating system running and controlling the hardware. Overview Virtual DOS machines can operate either exclusively through typical software emulation methods (e.g. dynamic recompilation) or can rely on the virtual 8086 mode of the Intel 80386 processor, which allows real mode 8086 software to run in a controlled environment by catching all operations which involve accessing protected hardware and forwarding them to the normal operating system (as exceptions). The operating system can then perform an emulation and resume the execution of the DOS software. VDMs generally also implement support for running 16- and 32-bit protected mode software (DOS extenders), which has to conform to the DOS Protected Mode Interface (DPMI). When a DOS program running inside a VDM needs to access a peripheral, Windows will either allow this directly (r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows XP
Windows XP is a major release of Microsoft's Windows NT operating system. It was released to manufacturing on August 24, 2001, and later to retail on October 25, 2001. It is a direct upgrade to its predecessors, Windows 2000 for high-end and business users and Windows Me for home users, available for any devices running Windows NT 4.0, Windows 98, Windows 2000 and Windows Me that meet the new Windows XP system requirements. Development of Windows XP began in the late 1990s under the codename "Neptune", built on the Windows NT kernel explicitly intended for mainstream consumer use. An updated version of Windows 2000 was also initially planned for the business market. However, in January 2000, both projects were scrapped in favor of a single OS codenamed "Whistler", which would serve as a single platform for both consumer and business markets. As a result, Windows XP is the first consumer edition of Windows not based on the Windows 95 kernel and MS-DOS. Windows XP removed suppo ...

Dir (command)
In computing, dir (directory) is a command in various computer operating systems used for computer file and directory listing. It is one of the basic commands to help navigate the file system. The command is usually implemented as an internal command in the command-line interpreter (shell). On some systems, a more graphical representation of the directory structure can be displayed using the tree command. Implementations The command is available in the command-line interface (CLI) of the operating systems Digital Research CP/M, MP/M, Intel ISIS-II, iRMX 86, Cromemco CDOS, MetaComCo TRIPOS, DOS, IBM/Toshiba 4690 OS, IBM OS/2, Microsoft Windows, Singularity, Datalight ROM-DOS, ReactOS, GNU, AROS and in the DCL command-line interface used on DEC VMS, RT-11 and RSX-11. It is also supplied with OS/8 as a CUSP (Commonly-Used System Program). The dir command is supported by Tim Paterson's SCP 86-DOS. On MS-DOS, the command is available in versions 1 and later.

Windows Explorer
File Explorer, previously known as Windows Explorer, is a file manager application that is included with releases of the Microsoft Windows operating system from Windows 95 onwards. It provides a graphical user interface for accessing the file systems. It is also the component of the operating system that presents many user interface items on the screen such as the taskbar and desktop environment, desktop. Controlling the computer is possible without Windows Explorer running (for example, the command in Task Manager on NT-derived versions of Windows will function without it, as will commands typed in a command prompt window). Overview Windows Explorer was first included with Windows 95 as a replacement for File Manager (Windows), File Manager, which came with all versions of Windows 3.x operating systems. Explorer could be accessed by double-clicking the new My Computer desktop icon or launched from the new Start Menu that replaced the earlier Program Manager. There is also a s ...
